Why is internal digection better than external? | Digestive systems take many forms. There is a fundamental distinction between internal and external digestion. External digestion developed earlier in evolutionary history, and most fungi still rely on it. In this process, enzymes are secreted into the environment surrounding the organism, where they break down an organic material, and some of the products diffuse back to the organism. Animals have a tube (gastrointestinal tract) in which internal digestion occurs, which is more efficient because more of the broken down products can be captured, and the internal chemical environment can be more efficiently controlled. | The next great advance in computing power came with the advent of the integrated circuit. The idea of the integrated circuit was first conceived by a radar scientist working for the Royal Radar Establishment of the Ministry of Defence, Geoffrey W.A. Dummer. Dummer presented the first public description of an integrated circuit at the Symposium on Progress in Quality Electronic Components in Washington, D.C. on 7 May 1952. | eng_Latn | 8,200 |
What is the abomasums close equivalent? | The abomasum is the fourth and final stomach compartment in ruminants. It is a close equivalent of a monogastric stomach (e.g., those in humans or pigs), and digesta is processed here in much the same way. It serves primarily as a site for acid hydrolysis of microbial and dietary protein, preparing these protein sources for further digestion and absorption in the small intestine. Digesta is finally moved into the small intestine, where the digestion and absorption of nutrients occurs. Microbes produced in the reticulo-rumen are also digested in the small intestine. | Often 'b' & 'p' are interchangeable, for example 'baggage' becomes 'pagas', 'lob' (to throw) becomes 'loopima'. The initial letter 's' is often dropped, for example 'skool' becomes 'kool', 'stool' becomes 'tool'. | eng_Latn | 8,201 |

Where are beta cells that attach to insulin located? | Traditionally, simple carbohydrates are believed to be absorbed quickly, and therefore to raise blood-glucose levels more rapidly than complex carbohydrates. This, however, is not accurate. Some simple carbohydrates (e.g., fructose) follow different metabolic pathways (e.g., fructolysis) that result in only a partial catabolism to glucose, while, in essence, many complex carbohydrates may be digested at the same rate as simple carbohydrates. Glucose stimulates the production of insulin through food entering the bloodstream, which is grasped by the beta cells in the pancreas. | In the months before the attack on Pearl Harbor, Kwajalein Atoll was the administrative center of the Japanese 6th Fleet Forces Service, whose task was the defense of the Marshall Islands. | eng_Latn | 8,203 |
What is chemical digestion? | Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream. Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use. | In 2007 the European Court of Human Rights (ECHR), noted in its judgement on Jorgic v. Germany case that in 1992 the majority of legal scholars took the narrow view that "intent to destroy" in the CPPCG meant the intended physical-biological destruction of the protected group and that this was still the majority opinion. But the ECHR also noted that a minority took a broader view and did not consider biological-physical destruction was necessary as the intent to destroy a national, racial, religious or ethnic group was enough to qualify as genocide. | eng_Latn | 8,204 |

Would digested food be an example of catabolism? | To put it in simple terms. Catabolism is a component of metabolism. So loosely speaking eating is indeed an example of catabolism because you eat food, it is broken down into smaller units that can be absorbed by your body. With that, the simple definition of catabolism is the breaking down of larger substances into its component parts. One thing that helps me understand catabolism is the opposite of catabolism: anabolism. Think of anabolic steroids, they make people build bigger muscles. Anabolism is the process by which things are built up. So the opposite is catabolism, "cutting down" larger substances into smaller ones.\n\nAlso, it is a process that occurs at the cellular level, using enzymes in the body.\n\nI hope this helps, I've tried to put it as straight forward as I know how. | i sat down to eat\nsome good old turkey meat\ni went to put it in my tongue\nbut spit it out cause it smelt like dung\nthen i went and tried \nthe green colored apple pie\nand let me tell you\nit tasted like doo-doo. | eng_Latn | 8,206 |
Hello all: \n Can any body tell me the principles of heterotrophic nutrition, plz elabortae | Heterotrophs are organisms which do not make their own food and instead use the food prepared by the autotrophs or the producers.There are three types of heterotrophic nutrition:\n\n1.Saprophytic:In this mode of nutrition,the organisms depend upon the dead and decaying organic(containing carbon or carbon chains) matter.they derive their nutritio from thesesaprophytic heterotrophs depend on dead, decaying organic matter. There are many species of saprophytic bacteria and fungi. Saprophytic decay bacteria and fungi are essential decomposers which recycle vital nutrients back into the ecosystem. .\n.eg - mushrooms,etc.\n\n2.Parasitic:In this mode of nutrition the organism dosn't pre[are its own food.It derives its food from some other organism.The organism fom which it derives its nutrition is called the host.eg\nParasitic nutrition: e.g. taenia (taenia solium - tapeworm). This is an endoparasite, with two hosts. The adult form is found attached on the inside of human intestines, the larval form is found in the pig. The adult is made up of segments called proglottides. At one end is the scolex, which has a double row of hooks and 4 suckers to attatch to the hosts intestine. Lower segments self fertilise and are released in the hosts faeces. It has no digestive system or enzymes it directly absorbs predigested nutrients straight into its body. It has a thick outer coating (tegument) made of protien and chitin, which protects it from the hosts enzymes. It can survive in low oxygen levels. It causes little damage in healthy humans.\n\nHolozoic:Organisms that are holozoic are consumers. Primary consumers are herbivores and Secondary consumers are carnivores, some organ isms feed on both plants and animals and are called omnivores.. Each are specifically adapted to their particular type of nutrition:\n\nHerbivores: e.g. cattle and sheep are herbivores and ruminants. Ruminants digestive systems allow a high proportion of cellulose to be digested. Ruminants have 4 stomachs (rumen, reticulum, omasum and abomasum).\n\n1) food is swallowed and lands in the rumen. This contains bacteria and some protoists annd yeasts. Food remains here for upto 30 hrs. The food is often regurgitated to be chewed again (chewing the cud). The microbes break down the cellulose (with cellulase), into hexoses (breaks poly saccaride b-link). These hexoses are then fermented in anaerobic conditions into organic acids, alos alot of CO2 and methane are belched.\n2) Next food enters the reticulum, sometimes food enters here first. Food moves between the rumen and reticulum fairly freely.\n3) As the food enters the omasum, where water and organic acids are removed. No enzymes are secreted.\n4) From here on it follows a similar path as in the human gut, with enzymes being secreted etc.\n\nNB. many of the bacteria etc are also taken in with the food and digested, which makes protien digestion from the rumen even more efficient, as the microbes can convert low grade protien and urea into a high grade version that can be digested by the cow.\n\nCarnivores: e.g. cat or dog. Their digestive system is more or less the same as humans. The greatest differences being in theeir dentition and other physical and behavioural adaptations which aid their hunting. | There is NO WAY I'm going to do your homework for you.

what is the test name for pancreas | Tests For Detecting Pancreatic Cancer. Secretin Pancreatic Function Test. Secretin pancreatic function test is a test that is primarily focused on the hormone 'secretin' that triggers the secretion of a fluid that neutralizes stomach acids and assists in digestion. | More about the tests used for both types of pancreatitis: 1 Amylase is the pancreatic and salivary gland enzyme responsible for digesting carbohydrates. 2 Lipase is the pancreatic enzyme that, along with bile from the liver, digests fats. 3 Trypsin is the pancreatic enzyme that digests proteins. | eng_Latn | 8,212 |
what starts digestion | Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food; the saliva also contains mucus, which lubricates the food, and hydrogen carbonate, which provides the ideal conditions of pH (alkaline) for amylase to work. | Stop 1: The Mouth. The mouth is the beginning of the digestive system, and, in fact, digestion starts here before you even take the first bite of a meal. The smell of food triggers the salivary glands in your mouth to secrete saliva, causing your mouth to water. When you actually taste the food, saliva increases. | eng_Latn | 8,213 |
what does the stomach do? | The stomach produces and secretes several important substances to control the digestion of food. Each of these substances is produced by exocrine or endocrine cells found in the mucosa. 1 The main exocrine product of the stomach is gastric juice â a mixture of mucus, hydrochloric acid, and digestive enzymes. | The stomach is a muscular, J-shaped organ in the abdomen.

how is bile used in the digestive system | Bile is a liquid produced by the liver and stored in the gallbladder that aids in the digestion of lipids and transports waste. Bile normally drains from the liver through a number of bile ducts to the duodenum and eventually back to the bile ducts and liver.ile is a fluid made by the liver and stored in the gallbladder. Bile is excreted into the small intestine, where it helps digest fat.\. This answer is based on source information from National Cancer Institute. | Bile is a digestive fluid made by the liver, stored in the gallbladder, and discharged into duodenum after food is ingested to aid in the digestion of fat. Normally, the pyloric sphincter prevents bile from entering the stomach.hile bile reflux involves fluid from the small intestine flowing into the stomach and esophagus, acid reflux is backflow of stomach acid into the esophagus. These conditions are often related, and differentiating between the two can be difficult. | eng_Latn | 8,217 |
functions of the pancreas in digestion | The Pancreas and Digestion. Exocrine cells of the pancreas produce enzymes that help with digestion. When food enters the stomach, exocrine cells release the pancreatic enzymes into a system of small ducts that lead to the main pancreatic duct. | Pancreas Function. Measuring about 12 to 15 centimeter in length, pancreas is a glandular organ lying behind stomach in the abdomen and performing both endocrine as well as exocrine functions. The exocrine secretions (pancreatic juice) are released into the duodenum of small intestine through pancreatic duct. | eng_Latn | 8,218 |
digestion of protein occurs in your stomach | Protein digestion occurs in the stomach and duodenum in which 3 main enzymes, pepsin secreted by the stomach and trypsin and chymotrypsin secreted by the pancreas, break down food proteins into polypeptides that are then broken down by various exopeptidases and dipeptidases into amino acids.igestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma.

the mouth participates in what type of digestion | Breaking Down Digestion. The digestion process is a combination of chemical and mechanical digestion. Chemical digestion breaks down food via a chemical change, in which the digestive juices and enzymes break down food into components small enough to enter the GI tract, the blood cells or the lymph cells. | Lipid digestion begins in the mouth, continues in the stomach, and ends in the small intestine. Enzymes involved in triacylglycerol digestion are called lipase (EC 3.1.1.3). They are proteins that catalyze the partial hydrolysis of triglycerides into a mixture of free fatty acids and acylglycerols. | eng_Latn | 8,222 |
what does the chemical digestion | Your body utilizes two types of digestion: chemical digestion and mechanical digestion. Chemical digestion refers the to the breakdown of food in the mouth, stomach and intestines through the use of acids and enzymes. Mechanical digestion processes--such as chewing, swallowing and the muscular movements that move food through the digestive tract--support chemical digestion by physically breaking whole foods into smaller pieces to facilitate chemical breakdown. | Summary: 1. Mechanical digestion refers to the digestion process that breaks the food into smaller particles. 2. Chemical digestion is the process where acids, bases and enzymes released into the digestive track responds to semi-solid food lumps.3.he process of taking the food from mouth to the body is called ingestion. The teeth initiates the mechanical digestion by grinding the food and this process is also called as masticating. When initiating the chemical digestion process, the saliva secreted helps in softening the food into semi-solid lump. | eng_Latn | 8,223 |

what helps digest protein | During the digestion process of proteins, the nutrient is broken down into the bodyâs usable form of protein, called amino acids. This process begins once the food or protein supplement reaches your stomach and continues into your small intestines. Most of the amino acid absorption occurs within the small intestine. Proteins absorb at varying rates. Whey protein is one of the fastest-absorbing proteins, and it absorbs at a rate of up to 10 grams per hour. By consuming less protein on a more frequent basis, you can improve the amount of protein your body absorbs. | Proteins are digested in the stomach and small intestine. Protease enzymes break down proteins into amino acids. Digestion of proteins in the stomach is helped by stomach acid, which is strong hydrochloric acid. This also kills harmful micro-organisms that may be in the food. | eng_Latn | 8,284 |
name the valve located between the stomach and the duodenum | Pyloric Sphincter. The pyloric sphincter is a band of smooth muscle at the junction between the pylorus of the stomach and the duodenum of the small intestine. It plays an important role in digestion, where it acts as a valve to controls the flow of partially digested food from the stomach to the small intestine.he pyloric sphincter prevents the regurgitation of chyme from the duodenum into the stomach. It also controls the flow of chyme into the intestine, which provides the intestines with a manageable volume of chyme from which to absorb nutrients. | The duodenum is the first of the three parts of the small intestine and continues from the pylorus of the stomach. It is the shortest part of the small intestine, measuring approximately 25 centimeters in length and is also the most important site of digestion as the pancreatic enzymes and bile empty into the duodenum. | eng_Latn | 8,285 |
how does food move through intestines | Propulsion. Two types of movements are responsible for moving food from your stomach to your intestines. The first is called propulsion -- moving your food forward, from your esophagus into your stomach and from your stomach to your small intestine. This movement requires a lot of muscle. Think about propulsion like squeezing a toothpaste tube. When you squeeze at the top, the toothpaste moves down. | Food is propelled through your small intestine by peristalsis, which is a wavelike series of muscular contractions. You might recall that peristalsis is also how food moves through your esophagus as it travels from the throat to the stomach. During peristalsis, the longitudinal muscles within the small intestine wall contract, and then the circular muscles contract, pushing the food down the tract. This coordinated contraction of smooth muscle keeps food moving on its one-way path through your digestive system. | eng_Latn | 8,286 |
do we need our pancreas | What is the pancreas? Do we need it? The pancreas is located just in front of our spine; behind the stomach lies a 6 inches long organ called the pancreas. Our pancreas is a very important organ in our body since it both has the endocrine (production of hormones) and exocrine (production of digestive enzymes) function. | The pancreas is a glandular organ that produces a number of hormones essential to the body. It forms an integral part of the digestive system. The pancreas is located below and behind the stomach, in the curve of the duodenum, which is a part of the small intestine. The pancreas secretes fluids that help break down food in the small intestine, along with bile and other fluids that aid the metabolism of fats and proteins. The pancreas is also critical to the production of insulin and glucagon, which regulate glucose levels in the blood. If the pancreas stops producing insulin, this leads to diabetes and a number of associated health issues. | eng_Latn | 8,287 |
what are the primary functions/responsibilities of the digestive system | The primary function of the digestive system is to break down the food we eat into smaller parts so the body can use them to build and nourish cells and provide energy. The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. Inside this tube is a lining called the mucosa. | Confidence votes 259. The primary function of the digestive system is to break down the food we eat into smaller parts so the body can use them to build and nourish cells and provide energy. The digestive system is a series of hollow organs joined in a long, twisting tube from the mouth to the anus.wo solid organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes. In addition, parts of other organ systems (for instance, nerves and blood vessels) play a major role in the digestive system. | eng_Latn | 8,288 |

the difference between mechanical and chemical digestion | Summary: 1. Mechanical digestion refers to the digestion process that breaks the food into smaller particles. 2. Chemical digestion is the process where acids, bases and enzymes released into the digestive track responds to semi-solid food lumps. 3. | The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use. In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication (chewing), a form of mechanical digestion, and the wetting contact of saliva. | eng_Latn | 8,290 |
food goes through the following organs in a specific order | The small intestine is the 'work horse' of digestion, as this is where most nutrients are absorbed. Peristalsis is also at work in this organ, moving food through and mixing it up with the digestive secretions from the pancreas and liver, including bile.he food then enters the esophagus. The esophagus is a muscular tube extending from the pharynx and behind the trachea to the stomach. Food is pushed through the esophagus and into the stomach by means of a series of contractions called peristalsis. | Movement of food through the system. The large, hollow organs of the digestive tract contain a layer of muscle that enables their walls to move. The movement of organ walls can propel food and liquid through the system and also can mix the contents within each organ. Food moves from one organ to the next through muscle action called peristalsis. | eng_Latn | 8,291 |
does stomach gas pass into the colon | Gas in the digestive tract - the esophagus, stomach, small intestine, and large intestine - comes from two sources: 1 Swallowed air. Normal breakdown of certain undigested foods by harmless bacteria naturally present in the large intestine, also called the colon. | Dealing with gas during pregnancy. During digestion, food particles pass from the stomach to the small intestine, where the large majority of food absorption takes place. Then, undigested particles pass into the large intestine and the colon, where bacteria break the rest of it down. | eng_Latn | 8,292 |
where is the stomach located | The stomach is a rounded, hollow organ located just inferior to the diaphragm in the left part of the abdominal cavity. Located between the esophagus and the duodenum, the stomach is a roughly crescent-shaped enlargement of the gastrointestinal tract. | Picture of the Stomach. © 2009 WebMD, LLC. All rights reserved. The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach. | eng_Latn | 8,293 |
what substances does your pancreas release to help in digestion | The bulk of the pancreas is composed of âexocrineâ cells that produce enzymes to help with the digestion of food. These exocrine cells release their enzymes into a series of progressively larger tubes (called ducts) that eventually join together to form the main pancreatic duct.he islets of Langerhans are the endocrine (endo= within) cells of the pancreas that produce and secrete hormones such as insulin and glucagon into the bloodstream. The pancreatic hormones, insulin and glucagon, work together to maintain the proper level of sugar (glucose) in the blood. | The pancreas does two main things: 1 It releases powerful digestive enzymes into the small intestine to aid the digestion of food. 2 It releases the hormones insulin and glucagon into the bloodstream. 3 These hormones help the body control how it uses food for energy. | eng_Latn | 8,294 |
does chemical digestion occur in the large intestine | The large intestine does not digest food. It simply is used to absorb water and compact the stool.

what organ will secrete sodium bicarbonate to neutralize the acidity of chyme in the small intestine | Function. The exocrine secretion of the pancreas consists of enzymes that digest food in the small intestine, and sodium bicarbonate to neutralize hydrochloric acid from the stomach in the duodenum. See: pancreatic juice. The islets of Langerhans contain alpha, beta, and delta cells. | A ring of muscle called a rictus sphincter controls the passage of food from the stomach into the caecum small intestine, where gall bile and pancreatic juice are secreted. Hydrochloric acid sodium bicarbonate is also secreted here to make the chyle chyme acidic alkaline. | eng_Latn | 8,297 |
what enzyme initiates the process of starch digestion in the mouth? | Digestion of starch starts in the mouth. Ptyalin enzymes convert starch into sugar in the process of mastication and in-salivations. Secretions from saliva accompany food and salivary starch digestion continues in the stomach. This takes long time for food to digest if it is eaten in correct conditions. | Amylase, an enzyme found in your mouth breaks starch into simple sugars. Amylase continues the work begun in the mouth by ptyalin and completes the process of breaking down a starch into single glucose molecules. Ptyalin breaks down a polysaccharide (starch) into a disaccharide (maltose).Amylase finishes the break-down by splitting the two glucose molecules in maltose into single glucans.It does this through the process of hydrolysis.tyalin breaks down a polysaccharide (starch) into a disaccharide (maltose).
