Which of the following would accompany a high-fat meal moving through the digestive system?

the release of gastrin, which triggers the liver to release bile
the release of gastrin, which triggers the stomach to release pepsin
the release of secretin, which triggers the liver to release bile
the release of secretin, which triggers the stomach to release pepsin

The answer is The release of secretin, which triggers the liver to release bile.

Secretin is the hormone released from the duodenum. It signals the secretion of bile in the liver. Bile helps digestion of lipids in the stomach.
Through the process of elimination:
- Pepsin is a hormone that breaks down proteins to the smaller peptides. So, pepsin does not breaks down lipids of high-fat meal.
- Gastrin is a hormone that triggers the gastric glands to secrete hydrochloric acid and pepsinogen, inactive form of pepsin.

The first statement is
