Gastric secretion is enhanced by very low pH (below a pH of 2). Gastric secretion can be stimulated before food has entered the mouth. Select the correct statement about digestive processes. Chyme entering the duodenum can decrease gastric motility via the enterogastric reflex.
The gastric phase begins when food enters the small intestine 3. Once activated, stretch receptors and chemoreceptors in the stomach trigger the flow of gastric juices and peristalsis.
The sight, smell, taste or thought of food can initiate the cephalic phase of gastric activity 2. The gastric phase begins when food enters the small intestine 3. Once activated, stretch receptors and chemoreceptors in the stomach trigger the flow of gastric juices and peristalsis. 4. The intestinal phase reflexes inhibit gastric activity. 5.
Secreted by glands in the tongue; begins breakdown of triglycerides in the stomach Lingual lipase Microvilli of th small intestine that increase surface area for absorption; also contain some digestive enzymes Brush border Finger-like projections of the mucosa of the small intestine that increase surface area for digestion and absorption
Chemical digestion: splitting food molecules into simple substances by hydrolysis with the assistance of digestive enzymes. b. motility: mechanical processes that break apart ingested food into small molecules. c. ingestion: taking foods and liquids into the mouth.
1. Segmentation in the small intestine help propel chyme through the intestinal tract. 2. The migrating motility complex is a type of peristalsis in the small intestine. 3. The large surface area for absorption in the small intestine is due to the presence of circular folds, villi, and microvilli. 4.
The mucous-producing cells of the small intestine are paneth cells. 5. Most long-chain fatty acid in monoglyceride absorption in the small intestine requires the presence of bile salts. 2, 3, 5. 2. The migrating motility complex is a type of peristalsis in the small intestine. 3.
