What is the maturation and life cycle of enterocytes (crypts, villi, sloughing etc.) - correct answer The crypts which located in the pits of villi contain stem cells that can differentiate to enterocytes, and the enterocytes mature as they migrate up. The life cycle of enterocytes is 72 hours. Once enterocytes have reached the top of villi, they are sloughed off, and are either digested or excreted in feces. Uptake - correct answer compounds being transported into enterocytes Absorption -...
