A) The intracellular enzymes digest important cellular constituents, causing the cells to disintegrate and slough.
B) The body needs a continual supply of protein derived from the digestion of these cells.

Epithelial cells on the villi are continually being shed because new cells are continually being produced in the crypts at the base of the villi and migrate upward. This turnover helps to maintain the integrity and function of the villi, which are responsible for nutrient absorption in the small intestine.
