Which organ removes toxins from the blood and helps turn food into fuel and nutrients?

• A. Liver.
• B. Gallbladder.
• C. Pancreas.
• D. Spleen.

Answer: (A)

Detoxifying the blood while turning digested food into usable energy and nutrients is a key function of the liver. It cleanses the bloodstream by metabolizing toxins such as drugs and alcohol, making them easier to eliminate in urine or bile. At the same time, it processes nutrients absorbed from the gut, converting them into energy and stores: it glycogen stores glucose when plentiful and releases it when needed, and it manages fat and protein metabolism to supply the body's needs. The liver also produces bile, which helps digest fats and further aids in nutrient utilization.

Other organs have different primary roles. The gallbladder mainly stores and concentrates bile; the pancreas provides digestive enzymes and hormones; the spleen supports immune function and filters blood—none are primarily responsible for both toxin removal from blood and converting food into fuel and nutrients like the liver does.
