Gallbladder

The gallbladder is a small, pear-shaped organ located beneath the liver. Its main function is to store and concentrate bile, a digestive fluid produced by the liver. When we eat, the gallbladder releases bile into the small intestine to help with the digestion and absorption of fats.

Structure of the Gallbladder

The gallbladder consists of three main parts: the fundus, body, and neck. It is made up of smooth muscle tissue and has a lining that can absorb water and electrolytes from bile, concentrating it.

Functions of the Gallbladder

Bile Storage: The gallbladder stores bile produced by the liver, allowing it to be concentrated and released in response to the presence of fatty foods in the small intestine.
Bile Concentration: The gallbladder absorbs water and electrolytes from bile, making it more concentrated and effective in the digestion of fats.
Bile Release: When fatty foods are detected in the small intestine, the gallbladder contracts and releases bile into the duodenum, aiding in the digestion and absorption of fats.

Common Gallbladder Disorders

Some common disorders of the gallbladder include:

Gallstones: Hardened deposits that can form in the gallbladder, causing pain and blockages.
Cholecystitis: Inflammation of the gallbladder, often due to gallstones or infection.
Biliary Dyskinesia: A condition where the gallbladder does not function properly, leading to abdominal pain and digestive issues.
