HCL, intrinsic factor and gastroferrin
3
Q
what do enterochromaffin like cells secrete
A
Histamine
4
Q
role of histamine in stomach
A
stims HCL production
5
Q
what do g cells produce
A
gastrin - released into blood
6
Q
what do d cells produce
A
somatostatin - released into blood
7
Q
role of intrinsic factor
A
binds B12 allowing absorption
8
Q
role of gastroferin
A
binds Fe allowing absorption
9
Q
role of HCL in stomach
A
converts pepsinogen (chief cells) to pepsin
10
Q
role of gastrin and somatostatin
A
gastrin - stims HCL and motility
somatostatin - inhibits HCL secretion
