question 74 (0.5 points)
which of the following induce the acinar cells of the pancreas to synthes release enzyme - rich exocrine secretions into the duodenum and causes contraction?
○ hcl
○ cck
○ alpha cells
○ intrinsic factor

Explanation:

To determine the correct answer, we analyze each option:

• HCl (hydrochloric acid) is in the stomach and doesn't directly induce pancreatic acinar cell enzyme secretion.
• CCK (Cholecystokinin) is a hormone that stimulates pancreatic acinar cells to secrete enzyme - rich exocrine secretions and also causes gallbladder contraction.
• Alpha cells are in the pancreas (islets of Langerhans) and secrete glucagon, not related to pancreatic exocrine secretion or gallbladder contraction.
• Intrinsic factor is produced by gastric parietal cells and is for vitamin B12 absorption, not related to this process.

So the correct option is the one related to the hormone that induces the described pancreatic and gallbladder actions.

Answer:

B. CCK
