Which hollow organ positioned beneath the liver collects and stores bile and releases it into the intestine to aid digestion?

• A. Stomach
• B. Pancreas
• C. Small intestine
• D. Gall bladder

Answer: (D)

The gallbladder is a hollow sac tucked under the liver. Its job is to store and concentrate bile, a digestive fluid produced by the liver, until it’s needed. When you eat fats, hormones signal the gallbladder to contract and release bile through the bile ducts into the small intestine (duodenum). There, bile emulsifies fats, making them easier to digest with pancreatic enzymes. The stomach mainly stores and digests food there; the pancreas makes digestive enzymes but doesn’t store bile; the small intestine is where digestion and absorption occur. So, the organ that collects, stores, and releases bile to aid digestion is the gallbladder.
