Document Summary
Inactivates salivary amylase: activates lingual lipase, activates pepsin, kills microbes, denatures proteins (unwraps folded structure, stimulates secretion of hormones. Secretion: mucus/bicarbonate, pepsinogen, gastric-lipase, intrinsic factor, hcl and gastrin. Digestion: salivary amylase inactivated by acid (hcl), lingual lipase activated by acid (hcl), pepsin begins protein digestion. List and describe the 3 regions of the small intestine: duodenum: functions to regulate how fast/slow digestion and absorption occurs (most digestion occurs here) Jejunum: most nutrient absorption takes place here (has many villi) Ileum: less nutrient absorption (less villi) but can absorb nutrients if necessary. What are the layers of the small intestine? (going from inside to outside) Is the muscular movement (forward and backward motion) that takes place in the small intestine. Used to increase the interactions between the chyme and absorptive cells. What is peristalsis: the movement of the bolus down the esophagus in one direction, the movement of chyme through the small intestine after segmentation.
