- What are some of the major differences between the mouseand human gastrointestinal systems?arrow_forwardName the major organs of the digestive system. Digestion (di-jest′yun) is the mechanical and chemical breakdown of foods and the absorption of the resulting nutrients by cells. Mechanical digestion breaks large pieces of food into smaller ones without altering their chemical composition. Chemical digestion breaks down larger nutrient molecules into simpler chemicals. The organs of the digestive system carry out these processes. The digestive system consists of the alimentary canal (al″i-men′tar-e kah-nal′), extending from the mouth to the anus, and several accessory organs that secrete into the canal substances that are used in digestion. The alimentary canal (from beginning to end) includes the mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum, and anus. The accessory organs include the salivary glands, liver, gallbladder, and pancreas (fig. 15.1; see reference plates 4, 5, and 6).
