Digestive System By :Isaac Gomez Mouth The animals open part of the mouth Stomach The internal organ in which the first part of digestion occurs, being (in humans and many mammals) a pear-shaped enlargement of the... Esophagus • a muscular passage connecting the mouth or pharynx with the stomach in invertebrate and vertebrate animals; gullet. Small intestine • The part of the intestine that runs between the stomach and the large intestine; the duodenum, jejunum, and ileum collectively Large Intestine The cecum, colon, and rectum collectively Liver A large lobed glandular organ in the abdomen of vertebrates, involved in processing digestive products, neutralizing toxins, and other... Appendix A tube-shaped sac attached to and opening into the lower end of the large intestine in humans and some other mammals. Pancreas A large gland behind the stomach that secretes digestive enzymes into the duodenum. Embedded in the pancreas are the islets of Langerhan... Gall Bladder gallbladder: a muscular sac attached to the liver that stores bile (secreted by the liver) until it is needed for digestion. Enzymes A substance produced by a living organism that acts as a catalyst to bring about a specific biochemical reaction. Most enzymes are... Bile/Bile Duct a large duct that transports bile from the liver to the duodenum, having in humans and many other vertebrates a side branch to a gallbladder for bile storage Mucus A slimy substance, typically not miscible with water, secreted by mucous membranes and glands for lubrication, protection, etc. Chemical Digestion Digestion is the mechanical and chemical breaking down of food into smaller components that can be absorbed into a blood stream, for... Absorption The process or action by which one thing absorbs or is absorbed by another: "shock absorption". Mechanical Digestion • The breaking of food into digestible chunks, normally using the teeth Salivary Amylase • Amylase is an enzyme that breaks starch down into sugar. Amylase is present in human saliva, where it begins the chemical process of Villi • Any of numerous minute elongated projections set closely together on a surface, typically increasing its surface area for the absorption Gastric Juices • A thin, clear, virtually colorless acidic fluid secreted by the stomach glands and active in promoting digestion. Duodenum • The first part of the small intestine immediately beyond the stomach, leading to the jejunum. Chyme • The pulpy acidic fluid that passes from the stomach to the small intestine, consisting of gastric juices and partly digested food.
