Describe the structure and the function of the stomach. Be sure to include cells and tissues relating to this organ.
Vikentia [17]

Connective tissues support the tissues of the mucosa and connect it to the muscularis layer.

The blood supply of the submucosa provides nutrients to the wall of the stomach. Nervous tissue in the submucosa monitors the contents of the stomach and controls smooth muscle contraction and secretion of digestive substances.

<h3>What is the function of the stomach?</h3>

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.

Thus, this could be the answer.
