what is bodel | Bodel Early Origins. The surname Bodel was first found in Prussia, where the name Bodecker was closely identified in early mediaeval times with the feudal society of early Europe. | In digestion, a bolus (from Latin bolus, ball) is a ball-like mixture of food and saliva that forms in the mouth during the process of chewing, (which is largely an adaptation for plant-eating mammals). It has the same color as the food being eaten, and the saliva gives it an alkaline pH. Under normal circumstances, the bolus is swallowed, and travels down the esophagus to the stomach for digestion. Once the bolus reaches the stomach, it mixes with gastric juices and becomes chyme, which then travels through the intestines for further digestion and absorption, and eventual discharge (as feces). | eng_Latn | 8,310 |

what are the human digestive tract organs | 411 The human digestive system is made up of a group of organs working together. The digestive tract is made up of the mouth, esophagus, stomach, small intestine, and the large intestine. There are also associated organs that support the digestive tract, such as; the liver, gall bladder, and the pancreas. | Digestive Organs. The digestive system is a group of organs (Buccal cavity (mouth), pharynx, oesophagus, stomach, liver, gall bladder, jejunum, ileum and colon) that breakdown the chemical components of food, with digestive juices, into tiny nutrients which can be absorbed to generate energy for the body.igestive Organs.

In humans, it is located in the abdominal cavity behind the stomach. It is an endocrine gland producing several important hormones, including insulin, glucagon, somatostatin, and pancreatic polypeptide which circulate in the blood. | eng_Latn | 8,385 |
what participates in protein digestion within the stomach? | Digestion of Proteins in the Stomach. Two of the substances secreted by the stomach, HCl (hydrochloric acid) and pepsinogen, interact to create pepsin, an enzyme that plays a very important role in protein digestion.The process that takes place when proteins are disintegrated by the enzymes is called hydrolysis.igestion of Proteins in the Stomach.

what is a jejunum | The jejunum (/dÊɨËdÊuËnÉm/) is the second part of the small intestine in humans and most higher vertebrates, including mammals, reptiles, and birds.The jejunum lies between the duodenum and the ileum.The jejunum is considered to begin at the attachment of the suspensory muscle of the duodenum to the duodenum, a location called the duodenojejunal flexure. The division between the jejunum and ileum is not anatomically distinct.he jejunum lies between the duodenum and the ileum. The jejunum is considered to begin at the attachment of the suspensory muscle of the duodenum to the duodenum, a location called the duodenojejunal flexure. | Partially digested food, or chyme, from the stomach is mixed with bile from the liver and pancreatic juice from the pancreas to complete its digestion in the duodenum. The jejunum is the middle section of the small intestine that serves as the primary site of nutrient absorption. It measures around 3 feet in length. | eng_Latn | 8,387 |
how do the digestive system and endocrine system work together | A: The digestive and endocrine systems work together, mostly through the pancreas, to produce and disseminate digestive enzymes. The endocrine system contains several different organs and glands, which are the hypothalamus, pituitary, parathyroids, adrenal glands, reproductive glands, thyroid and pineal body. The primary role of the endocrine system is to produce important hormones that tell the digestive system when to start digesting food and when to stop. Continue Reading | The nervous system and the endocrine system works together to coordinate the activity of different body parts. The nervous system is the first to react to internal and external stimuli, whereas the endocrine system kicks in later but its effects stay for long. Together, they help maintain homeostasis. 5.

what plants contain maltase | The action of animal (salivary and pancreatic) as well as plant (germinating cereals, sweet potato) amylases on starch, dextrin, and glycogen produces maltose as the main end product. Maltose is hydrolyzed by acids and the enzyme maltase to two molecules of d -glucose. See Glucose, Maltase, Oligosaccharide. | This enzyme acts on the remaining polysaccharides and breaks them into disaccharide units of maltose. In the final step of complex carbohydrate digestion, the enzyme maltase present in the lining of the small intestine breaks maltose into two units of glucose.Glucose is then absorbed and enters the bloodstream.lthough fiber resists enzyme action and is not broken down during digestion, break down of starch by enzymes starts in the mouth. | eng_Latn | 8,389 |
what absorbs water from remaining food and transmits waste | The large intestine, also called the colon or the large bowel, is the last part of the digestive system in vertebrates. Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation. Terminologia Anatomica, Medscape, and Gray's Anatomy define the large intestine as the combination of the cecum, colon, rectum, and anal canal. | STAY INFORMED. Colon: The long, coiled, tubelike organ that removes water from digested food. The remaining material, solid waste called stool, moves through the colon to the rectum and leaves the body through the anus. Also known as large bowel and large intestine. | eng_Latn | 8,390 |
where is the jejunum located | Jejunum is the middle segment of the SMALL INTESTINE, between the ILEUM and the DUODENUM. The jejunum is six to eight feet long and handles absorption of carbohydrates and proteins, as well as vitamins such as VITAMIN K and minerals such as iron.ejunum is the middle segment of the SMALL INTESTINE, between the ILEUM and the DUODENUM.

where does the chemical digestion of proteins begin? | Confidence votes 106. Protein digestion in humans begins in the stomach. The enzyme pepsin is activated from its' inactive form pepsinogen due to the acidic conditions of the stomach. Pepsin starts digestion of proteins by breaking down the many of polypeptides into shorter peptides. However, complete chemical digestion will not occur until proteins reach the duodenum and the jejunum of the small intestine. Here more enzymes come into play (proteases and peptidases) so that the protein is completely broken down into its' smallest building blocks (the monomers called amino acids). | Protein digestion (by enzymes called proteases) begins in the stomach, where pepsin breaks down some proteins into polypeptides. The undigested proteins that enter the small iâ¦ntestines are digested by trypsin (another enzyme) into polypeptides. | eng_Latn | 8,393 |
where are nutrients absorbed | As food is processed along the digestive tract, most of the nutrients are absorbed through the walls of the small intestines. The nutrients are carried into the bloodstream where they can travel to all parts of the body. | The system in the body that absorbs nutrients is the digestive system. Within the digestive system is the small intestine. When food passes through the small intestine, vi ⦠lli, absorb all of the nutrients the body needs from the food. | eng_Latn | 8,394 |
where is saliva produced | Saliva is a watery substance located in the mouths of animals, secreted by the salivary glands. Human saliva is 99.5% water, while the other 0.5% consists of electrolytes, mucus, glycoproteins, enzymes, antibacterial, and bacteria compounds such as secretory IgA and lysozyme.The enzymes found in saliva are essential in beginning the process of digestion of dietary starches and fats.here is much debate about the amount of saliva that is produced in a healthy person per day; estimates range from 0.75 to 1.5 litres per day while it is generally accepted that during sleep the amount drops to almost zero. | The salivary glands located in the mouth produce saliva which helps in this mechanical breaking down and digestion. Saliva is made up of mucus, electrolyte, water and some digestive enzymes like amylase that are good in digesting starch and sugar.In the stomach, gastric juices are produced that are colorless and are highly acidic in nature. These are produced by the gastric glands present inside the stomach.he digestive tract system comprise of esophagus, mouth, stomach, small intestine and large intestine or colon, rectum and anus. A lining called as mucosa is present inside these hollow organs. The mucosa of mouth, small intestine and stomach contain tiny glands that generate digestive juices for food digestion. | eng_Latn | 8,395 |
what organ does gastric lipase come from | Lipase is a digestive enzyme produced by the following organs: pancreas (pancreatic lipase), liver (hepatic lipase), and stomach (stomach/gastric lipase). Enzymes are responsible for the metabolism of carbohydrates, proteins, and fats. | In humans, digestion begins in the stomach with the action of gastric lipase because humans do not have a lingual lipase [81]. Gastric lipase releases 10â30% of fatty acids before the fat emulsions pass into the intestine where they mix with bile lipids and digestive enzymes from the pancreas [82]. | eng_Latn | 8,396 |
is there any food or drink that will stimulate the pancreas to secrete insulin | 1 Parasympathetic nerves stimulate the release of insulin and pancreatic juice by the pancreas. 2 Pancreatic juice helps with the digestion of food while insulin stores the glucose released from the digested food in the bodyâs cells. | Step 3. Eat foods that contain folate, lycopene and healthy fat, such as olive oil. A variety of diseases and disorders can impair pancreas function. The pancreas secretes insulin, a hormone that plays an integral role in digestion. | eng_Latn | 8,397 |
what organs does food pass through | Food begins its journey through the digestive system in the mouth, before being pushed by a series of involuntary muscle contractions through the esophagus, then the stomach, and then the small and large intestines. | Food's Journey Through the Digestive System continued... The act of swallowing takes place in the pharynx partly as a reflex and partly under voluntary control. The tongue and soft palate -- the soft part of the roof of the mouth -- push food into the pharynx, which closes off the trachea.he 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. | eng_Latn | 8,398 |
which organ secretes the most potent of the digestive enzymes? | Pancreas. Pancreas is the storehouse of digestive enzymes and it is the main digestive gland of our body. The digestive enzymes of the pancreas breakdown carbohydrates and starch molecules to simple sugars. They also secrete a group of enzymes which help in degradation of nucleic acids. It functions both as an endocrine and exocrine gland. The digestive enzymes secreted by pancreas are listed in the table. | Digestive enzymes are secreted by different exocrine glands including: 1 Salivary glands. 2 Secretory cells in the stomach. 3 Secretory cells in the pancreas.4 Secretory glands in the small intestine. Pepsin breaks down the protein in the food into smaller particles, such as peptide fragments and amino acids. 2 Protein digestion, therefore, first starts in the stomach, unlike carbohydrate and lipids, which start their digestion in the mouth. | eng_Latn | 8,399 |
