Fig. 22.28

Acidic, fatty

chyme

enters duodenum.

In response,

enteroendocrine

cells

produce

secretin

and

cholecystokinin

(CCK).

These hormones enter

the circulation.

Secretin

stimulates

liver to make bile.

(note: Bile salts returning

from enterohepatic circulation are most powerful stimulus for bile secretion)

Secretin

stimulates pancreatic release of alkaline (HCO

3

-

) to neutralize acidic

chyme

(H

+

).

Cholecystokinin

stimulates pancreatic release of:

lipases (fat dig.)

amylase (carbo dig.)

trypsin (protein dig.)

Cholecystokinin

stimulates

gallbladder smooth muscle contractions to release bile

Cholecystokinin

causes

hepatopancreatic

sphincter to relax.

Bile and pancreatic juice enter duodenum.
