Portage Learning BIOD 151 Module 3 Exam Questions LATEST UPDATE RATED A+
Explain why someone who has hypergastrinemia (excessive secretion of gastrin) might develop gastric/stomach ulcers. Gastrin stimulates the secretions of pepsinogens and hydrochloric acid. Excess amounts would lead to erosion of the stomach lining. Question 2 5 / 5 pts Explain in detail how the stomach contents enter the small intestine. . The pyloric sphincter (valve), located at the base of the stomach, relaxes causing a small quantity of chyme to pass through the opening into the first part of the small intestine. This initiates a reflex that causes the muscles of the sphincter to contract and close the opening temporarily. Then the sphincter relaxes again and allows more chyme to enter.
