Question

question 17 1 pts the ejection of bile from the gallbladder is controlled by which hormones? gastrin and cck cck and gip cck and secretin secretin and gip

Explanation:

To determine the hormones controlling bile ejection from the gallbladder, we analyze each option:

• Gastrin (first option) mainly stimulates gastric acid secretion, not gallbladder bile ejection.
• GIP (in second and fourth options) regulates insulin release and gastric emptying, not gallbladder function.
• Cholecystokinin (CCK) causes gallbladder contraction to eject bile, and secretin enhances bile secretion (making bile more alkaline) and also interacts with CCK in gallbladder function regulation. So the correct pair is CCK and secretin.

Answer:

C. CCK and secretin (Note: Assuming the options are labeled as A: gastrin and CCK, B: CCK and GIP, C: CCK and secretin, D: secretin and GIP. If labels differ, adjust, but the content is CCK and secretin.)
