SLS Bio12 Digestion
SLS Bio12 Digestion KM
| Term | Definition |
|---|---|
| absorption | the process or action by which one thing absorbs or is absorbed by another |
| appendix | a tube-shaped sac attached to and opening into the lower end of the large intestine in humans and some other mammals. |
| bile | a bitter greenish-brown alkaline fluid that aids digestion and is secreted by the liver and stored in the gallbladder. |
| cardiac sphincter | the valve between the distal end of the esophagus and the stomach; the physiological sphincter at the esophagogastric junction |
| chemical digestion | Digestion is the mechanical and chemical breakdown of food into smaller components that are more easily absorbed into a blood stream, for instance. Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones |
| digestive enzyme | Digestive enzymes are enzymes that break down polymeric macromolecules into their smaller building blocks, in order to facilitate their absorption by the body. |
| duodenum | the first part of the small intestine immediately beyond the stomach, leading to the jejunum. |
| emulsification | the breakdown of large fat globules into smaller, uniformly distributed particles. It is accomplished mainly by bile acids in the small intestine. |
| epiglottis | a flap of cartilage at the root of the tongue, which is depressed during swallowing to cover the opening of the windpipe. |
| esophagus | the part of the alimentary canal that connects the throat to the stomach; the gullet. In humans and other vertebrates it is a muscular tube lined with mucous membrane |
| gall bladder | the small sac-shaped organ beneath the liver, in which bile is stored after secretion by the liver and before release into the intestine. |
| gastric juice | a thin, clear, virtually colorless acidic fluid secreted by the stomach glands and active in promoting digestion. |
| insulin | a hormone produced in the pancreas by the islets of Langerhans that regulates the amount of glucose in the blood. The lack of insulin causes a form of diabetes. |
| intestinal juice | secretions by glands lining the walls of the intestines |
| lacteals | the lymphatic vessels of the small intestine that absorb digested fats. |
| large intestine (colon) | The broad, shorter part of the intestines which from the end of the small intestine (ileum) to the anus. The large intestine is comprised of the colon, and rectum. |
| lipase | a pancreatic enzyme that catalyzes the breakdown of fats to fatty acids and glycerol or other alcohols. |
| maltase | an enzyme, present in saliva and pancreatic juice, that catalyzes the breakdown of maltose and similar sugars to form glucose. |
| microvillus | each of a large number of minute projections from the surface of some cells. |
| nuclease | an enzyme that cleaves the chains of nucleotides in nucleic acids into smaller units. |
| pancreas | a large gland behind the stomach that secretes digestive enzymes into the duodenum. |
| pancreatic amylase | Amylase is an enzyme that catalyses the hydrolysis of starch into sugars. Amylase is present in the saliva of humans and some other mammals, where it begins the chemical process of digestion |
| pancreatic juice | the clear alkaline digestive fluid secreted by the pancreas. |
| pepsin | the chief digestive enzyme in the stomach, which breaks down proteins into polypeptides. |
| pepsinogen | a substance that is secreted by the stomach wall and converted into the enzyme pepsin by gastric acid. |
| peptidase | an enzyme that breaks down peptides into amino acids. |
| peristalsis | the involuntary constriction and relaxation of the muscles of the intestine or another canal, creating wavelike movements that push the contents of the canal forward. |
| pharynx | the membrane-lined cavity behind the nose and mouth, connecting them to the esophagus. |
| physical digestion | The physical digestion has to do with the breakdown of food through physical means. The process involves grinding of food with the help of teeth. |
| protease | an enzyme that breaks down proteins and peptides. |
| pyloric sphincter | the sphincter muscle of the pylorus that separates the stomach from the duodenum |
| salivary amylase | Any of a group of enzymes that are present in saliva, pancreatic juice, and parts of plants and catalyze the hydrolysis of starch to sugar to produce carbohydrate derivatives. |
| salivary gland | any of three pairs of glands in the mouth and digestive system that secrete saliva for digestion |
| small intestine | the part of the intestine that runs between the stomach and the large intestine; the duodenum, jejunum, and ileum collectively. |
| sodium bicarbonate | a soluble white powder used in fire extinguishers and effervescent drinks and as a leavening agent in baking. |
| stomach | the internal organ in which the major part of the digestion of food occurs, being (in humans and many mammals) a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine. |
| trypsin | a digestive enzyme that breaks down proteins in the small intestine. It is secreted by the pancreas in an inactive form, trypsinogen. |
| villus | any of numerous minute elongated projections set closely together on a surface, typically increasing its surface area for the absorption of substances, in particular. |
