Question

What is the role of stomach in the digestion process?

Answer 1

The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food.The stomach muscles contract periodically, churning food to enhance digestion.

Answer 2

Hiiiiii machiiii ✋..


➡️ The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach.

➡️ The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.

➡️ Partial digestion of the food takes place here. The churning action of the stomach muscles physically breaks down the food.

➡️ The stomach releases acids and enzymes for the chemical breakdown of food. The enzyme pepsin is responsible for protein breakdown.
