-from tight junctions (BTB)
Corticonephrons - up near cortex of the kidney

of off Na+ ions. This is not passive, it is secondary
active. Then goes into fenstrated capillaries where it

Well the only similarity is that both the stomach and
S.I. have these enteroendocrine cells, but here are the
differences...

enteroendocrine cells in Stomach - the enteroendocrine cells in the stomach
the stomach to the small are mainly G-Cells which produce Gastrin which is
intestine. used to stimulate all the digestion in the stomach.
S.I. - secrete hormones CCK and Secretin. Secretin

which don't function.
As you age you have decreased parietal cell
production which is a decrease in Intrinsic Factor and
HCl, if we have a decrease in Intrinsic Factor than we
have a decrease in B-12 absorption.

Solutions- If your vegan, you can be given B-12 pills
and vegans have an issue

enough Intrinsic Factor to absorb it.
and what are the solutions
Solutions - If your old, this doesn't work. So you take
B-12 pills sub-lingual because there are lots of
capillaries here and goes into blood and bypasses
the digestive, this can be used for not just B-12.
