Terms to Know
Bile

A secretion created by the liver that is used to aid in the digestion of lipids (fats).

Gallbladder

The organ that stores bile until we need to secrete it; bile is transported from the gallbladder into the duodenum through bile ducts.

Hepatic Portal System

A system of veins that drain blood from the stomach and intestines to the liver; a portal system consists of two consecutive capillary beds connected by a portal vein(s).

Liver

The largest of the visceral organs, the liver produces bile and secretes it into the gallbladder to be stored. The liver also processes nutrients such as amino acids and carbohydrates and also “detoxifies” the blood.

Pancreas

A mixed organ (both endocrine and exocrine) that produces and secretes pancreatic juices into the small intestine that aid in the digestion of food.
