Video Summary
The gallbladder is a small, pear-shaped organ that sits just below the liver on the right side of the abdomen. The gallbladder's main function is to store bile, a fluid that helps digest fat. The gallbladder has three main layers: the mucosa consisting of the simple columnar epithelium; the tunica muscularis consisting of randomly oriented smooth muscles; and the outer connective tissue, referred to as serosa or adventitia.
