Question

Is there muscle tissue in the stomach?

Answer 1

Stomach muscles:

1. The stomach secretes the acid and enzymes which digest food.
2. Ridges of muscle tissue called rugae line the stomach.
3. The stomach muscles then contract periodically, churning the food to enhance digestion.
4. The pyloric sphincter is a muscular valve that opens to allow the food to pass from the stomach to the small intestine.
