Pancreas, liver, and gallbladder (accessory organs), assist the organs of the GI tract for processing food.
Gallbladder is a pear-shaped organ (a small pouch) just below the liver.
LIVER PRODUCES BILE AND GALLBLADDER STORES IT.
Gallbladder stores and concentrates bile (greenish-yellow/brownish fluid secreted by the liver) by removal of most of the water and delivers it to the duodenum via the bile ducts.
