Examine the gallbladder and identify its body, fundus and neck. The fundus and neck of the gallbladder are completely covered by visceral peritoneum. The anterior surface of the body of the gallbladder is attached to the right sagittal fossa of the liver. The posterior surface of the gallbladder is covered by visceral peritoneum.

Make a longitudinal incision along the wall of the gallbladder and examine its interior surface. This surface is usually stained by the dark green bile. It is not uncommon to find small calcified stones in the lumen.

Identify the cystic duct, which connects the gallbladder to the common bile duct. Observe the spiral mucosal folds, called the spiral valve, on its internal walls (Figure 38.6).
