Gallbladder volume changes described in the material?

• A. Volume unchanged
• B. Volume decreases
• C. Volume increases
• D. Volume fluctuates with meals

Answer: (C)

The gallbladder acts as a dynamic bile reservoir. It fills and concentrates bile between meals, so its volume is larger during fasting. When a meal is eaten, cholecystokinin triggers the gallbladder to contract and release bile into the small intestine, reducing its volume. Because it increases when fasting and decreases after meals, gallbladder volume fluctuates with meals.
