Which organ produces bile and detoxifies the blood?

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

Answer: (C)

The liver handles both bile production and blood detoxification. Bile is produced by liver cells (hepatocytes) and then secreted into bile ducts; it’s stored in the gallbladder and released into the small intestine as needed to emulsify fats. Detoxification happens in the liver through enzymatic processes that modify and neutralize toxins and drugs, and by converting substances like ammonia into urea for excretion. The blood that comes from the gut via the portal vein passes through the liver for processing before joining general circulation. The other organs don’t perform both roles: the stomach mainly secretes acid and digestive enzymes; the spleen focuses on filtering blood and immune functions; the gallbladder stores bile but does not detoxify. So, the organ that produces bile and detoxifies the blood is the liver.
