What is the digestive and storage role of the stomach in humans?

Function in Digestion: The stomach wall is made up of three main layers:

an external connective tissue layer

The middle layer of smooth muscles is made up of inner circular and outer logitudinal muscles, which work together to mix and churn food with stomach secretions.

Gastric juice is the collective term for the secretions of all these cells, and its secretion is influenced by the food's quality, smell, and appearance.

Consequently, the stomach's three layers carry out their designated roles in the partially digested food into a pulpy, acidic fluid called chyme. The stomach eventually empties into the duodenum when the pyloric sphincter relaxes.

Function as a food storage bag: The stomach is an organ that allows us to stop eating when we're hungry. Without it, I believe it would be impossible for us to survive. We would have to eat nonstop from sunrise to sunset.

The stomach processes ingested food through mechanical and chemical digestion. It stores and partially digests food, breaking it down into chyme before gradually releasing it into the small intestine.
