Q

Where is Bicarbonate produced and released?

A

Pancreas → Duodenum

23
Q

Gallbladder

A

Stores and releases bile into small intestine when needed

mucosal cells

38
Q

What does Cholecystokinin do?

A

slows down amount of material leaving stomach

39
Q

How is the GI tract part of the endocrine system?

A

GI Tract releases hormones that regulate speed & preparation of digestive system

40

A

…to sythesize structural, regulatory, or storage molecules.”

41
Q
