Anatomy
In the small intestine, villi protrude into the lumen to maximize contact for nutrient uptake. Likely, to counteract the frequent infections or the surface cells, the body heavily invests in the turnover of cells, specifically at the surface of the invaginations. In the small intestine, adult stem cells reside within the invaginations and constantly proliferate.
The small intestine, whose primary function is in nutrient digestion and absorption, begins at the pylorus just downstream of the stomach and ends at the ileocecal valve.
