Secretes enzymes for protein digestion

Stores and concentrates bile

Verified step by step guidance

Understand the primary functions of the stomach in the digestive system. The stomach is responsible for breaking down food through mechanical and chemical processes.

Recognize that the stomach secretes gastric juices, which include hydrochloric acid and digestive enzymes like pepsin, to aid in the digestion of proteins.

Differentiate the functions of the stomach from those of other digestive organs. For example, the liver produces bile, which is stored and concentrated in the gallbladder, not the stomach.

Identify that nutrient absorption primarily occurs in the small intestine, not the stomach. The stomach's role is more focused on digestion rather than absorption.

Conclude that the stomach's main function related to the options given is the secretion of enzymes for protein digestion, as it does not produce bile or absorb most nutrients.
