(a) Why are villi present in the intestine and not in stomach.
Answer
(a) Major portion of absorption of food takes place in small intestine. Absorption in small intestine is also important because digestion is almost complete by the time food reaches ileum. Villi increase the absorptive surface area for the absorption of digested food. The digested food is present in intestine only. The digested food is not present in stomach, therefore in this part there is no need of villi and thus, they are absent.
