Secretin
produced in the small intestine
Stimulates the production of bicarbonate by the pancreas
Insulin
produced in the pancreas
regulates blood sugar level
Glucagon

Enhances fat-soluble Vitamin A, D, E, and K
Stored and concentrated in gallbladdar

Peritoneal cavity
Fluid filled space between two peritoneum
fluid lubricates most organs
Mesentery
