Question

Discuss the structure and function of the gallbladder.

Expert Solution
Step 1: Introduction:

The gallbladder is a small pouch that sits just under the liver. The gallbladder stores bile produced by the liver. After meals, the gallbladder is empty and flat, like a deflated balloon. Before a meal, the gallbladder may be full of bile and about the size of a small pear.

Step 2: Structure of gallbladder:

The gallbladder is a pear-shaped, hollow structure located under the liver and on the right side of the abdomen. Its primary function is to store and concentrate bile, a yellow-brown digestive enzyme produced by the liver. The gallbladder is part of the biliary tract.

There are three main parts of the gallbladder:

Fundus — the large end that stores bile juices.

Body — not as large and begins to taper.

Neck — tapers further and connects to the cystic duct.
