Document Summary
Enzyme isn"t altered or changed in the reaction. Digestive tract & accessory organs make up the digestive system. Increases surface area of food for chem reactions. Submucosa: connective tissue, cont. blood vessels, nerves, etc. Muscularis: smooth muscle layers for movement and secretion. Parietal peritoneum: covers interior surface to body wall. Mesenteries: peritoneal (i. e. epithelial) tissue which connects organs together. Routes by which vessels and nerves pass from body wall to organs. Lesser omentum: connects stomach to liver and diaphragm. Retroperitoneal organs lie against the body wall and have no mesenteries. Simple columnar epithelium in small intestine (rapid secretion and absorption) Uvula: part of the soft palate, stops food entering the nasal cavity when swallowing. Two sets of teeth: primary (<2yrs) and secondary (>2yrs) Produces amylase, which breaks down carbohydrates, and the antibacterial lysozyme. Uvula (in soft palate) prevents food/drink from entering the nasopharynx. Esophagus connects pharynx to stomach, lies posterior to trachea.
