Question

Why villi is not present in stomach?

Answer 1

Answer:

One villus contains many cells and thereby increase the surface area (see image below). This is required because a lot of nutrients have to be absorbed in the small intestine. ... The stomach does not absorb any nutrients and therefore does not require a larger surface area.

Answer 2

Answer: the main purpose that villi serves in the intestine is to increase the absorptive surface area as no significant absorption occurs in the stomach so there is no requirement of villi in the stomach.
