life cycle is about 72 hours once it has entered the villus from the
crypt
Once at the tip of villus, mature enterocytes are sloughed off and
either digested or excreted.
Uptake - ANS-compound taken up into enterocyte
Absorption - ANS-compound moves from enterocyte into
circulation (blood or lymph)
Passive transport - ANS-does not require energy to move with
concentration gradient
Simple diffusion, osmosis, facilitated diffusion
simple diffusion - ANS-movement of solutes from higher
concentration to lower concentration without help of proteins
