What is the function of gallbladder?

The gallbladder is used to store and concentrate bile, secrete mucus, and regulate bile duct pressure.

1. Store and concentrate bile

. Bile produced by the liver flows through the bile duct to the gallbladder, which concentrates and stores it. When eating, the gallbladder contracts and drains bile into the duodenum through the bile duct to help digest food.

2. Secrete mucus. The

gallbladder secretes mucus to protect the bile duct mucosa from erosion and damage by bile.

3. Regulate bile duct pressure. The

gallbladder can regulate the pressure in the bile duct by expanding or contracting to help maintain the flow of bile.
