| Term | Definition |
|---|---|
| Monogastric | having a stomach with only a single compartment |
| Mouth | the natural opening through which food passes into the animal body and which in vertebrates is typically bounded externally by the lipsand internally by the pharynx and encloses the tongue, gums, and teeth |
| Esophagus | a muscular tube that leads from the mouth through the throat to the stomach |
| Small Intestine | the part of the intestine that lies between the stomach and colon |
| Cecum | the blind pouch at the beginning of the large intestine into which the ileum opens from one side and which is continuous with the colon |
| Large Intestine | the tubular part of the digestive tract that extends from the stomach to the anus |
| Ruminant | even-toed hoofed mammals (such as sheep, oxen, deer, and camels) that chew the cud and have a complex 3- or 4-chambered stomach |
| Rumen | the large first compartment of the stomach of ruminant from which food is regurgitated for rumination |
| Reticulum | the second compartment of the stomach of a ruminant in which folds of the mucous membrane form hexagonal cells |
| Omasum | the third chamber of the ruminant stomach that is situated between the reticulum and the abomasum |
| Abomasum | the fourth compartment of the ruminant stomach that follows the omasum and has a true digestive function |
| Salivary Gland | any of various glands that discharge a fluid secretion and especially saliva into the mouth cavity |
| Gallbladder | a membranous muscular sac in which bile from the liver is stored |
| Pancreas | a large gland of the body that is near the stomach and that produces insulin and other substances that help the body digest food |
| Cardiac Valve | any of the valves that control blood flow to and from the heart |
| Pyloric Valve | the muscular opening from the vertebrate stomach into the intestine |
| Villi | a small slender often vascular process: such as. a : one of the minute finger-shaped processes of the mucous membrane of the small intestine that serve in the absorption of nutriment |
| Absorption | the process of absorbing something |
| Alimentary Tract | the long tube in the body through which food passes after it is eaten |
| Accessory Digestive Organ | the bodily system concerned with the ingestion, digestion, and absorption of food and the discharge of residual wastes and consisting of the digestive tract and accessory glands (such as the salivary glands and the pancreas) that secrete digestive enzymes |
| Crop | a pouched enlargement of the esophagus of many birds that serves as a receptacle for food and for its preliminary maceration also : an enlargement of the digestive tract of another animal |
| Proventriculus | the glandular or true stomach of a bird that is situated between the crop and gizzard |
| Gizzard | a part in the stomach of a bird in which food is broken down into small pieces |
| Cloaca | the common chamber into which the intestinal and urogenital tracts discharge especially in monotreme mammals, birds, reptiles, amphibians, and elasmobranch fishes also : a comparable chamber of an invertebrate |
| Kidney | either of a pair of organs near the backbone that give off waste from the body in the form of urine and in humans are bean-shaped |
| Duodenum | the first part of the small intestine extending from the pylorus to the jejunum |
| Pharynx | the part of the neck in front of the spinal column |
| Yolk Sac | the yolk sac of a mammalian embryo usually having the form of a fluid-filled pouch, corresponding to the yolk sac of an oviparous vertebrate, and having a transitory connection with the digestive tract by way of the omphalomesenteric duct |
| Lleocecal Valve | the valve formed by two folds of mucous membrane at the opening of the ileum into the large intestine |
| Liver | a large lobed glandular organ in the abdomen of vertebrates, involved in many metabolic processes |
| 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 |
