Question
Why are villi present in the intestine and not in the stomach?

Solution
In the small intestine digestion gets completed and the absorption of digested food materials like glucose, amino acids, fatty acids, and glycerol takes place. The food materials are to be retained in the intestine by increasing the surface area. Hence villi are present in the intestine. The stomach is the temporary storing organ of food. In the stomach, HCl, pepsin, renin, and lipase are secreted. These are concerned with digestion. Hence villi are not present in the stomach.
