**Question:** The normal capacity of the gallbladder is:

A. 30-50 ml
B. 100 ml
C. 100-200 ml
D. 200-300 ml

**Core Concept:** The gallbladder is a small, pear-shaped organ located in the right hypochondrium, responsible for storing and concentrating bile produced by the liver. Bile is essential for the digestion and absorption of lipids in the small intestine.

**Why the Correct Answer is Right:** The correct answer (A) 30-50 ml represents the approximate normal capacity of the gallbladder, which is sufficient to store and concentrate bile for a few hours, ensuring a steady supply to the small intestine during digestion.

**Why Each Wrong Option is Incorrect:**

B. 100 ml (too large) - The gallbladder's volume is relatively small to minimize the risk of complications associated with its enlargement (e.g., cholecystitis, cholelithiasis).

C. 100-200 ml (too large) - Similar to option B, having a larger gallbladder capacity increases the risk of complications.

D. 200-300 ml (too large) - This option is incorrect because a larger gallbladder capacity can lead to complications.

**Clinical Pearl:** An understanding of the normal gallbladder capacity helps in assessing abnormal findings during clinical examination or imaging studies, such as ultrasound, which may indicate gallbladder pathology (e.g., cholecystolithiasis, cholecystitis).

**Correct Answer:** A. 30-50 ml
