Life of enterocytes - Study guides, Class notes & Summaries

What is the maturation and life cycle of enterocytes (crypts, villi, sloughing etc.) correct answers 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 answers compounds being transported into enterocytes Absorption cor...

Life of Enterocytes - In the crypts of Lieberkuhn (the pits between villi), stem cells are produced which can create enterocytes. As the cells mature, they migrate to the top of the villi, and thus the most mature are on the tips of the villi. 72 hours after an enterocyte enters the villi from the crypt, they are "sloughed off" and excreted in feces. If not sloughed off, they will be digested and the components (proteins and lipids) will be taken up by remaining enterocytes still on villi. ...
