Which of the following is a function of the liver other than the manufacture of bile?

• A. Detoxification
• B. Storage of fats
• C. Hormone secretion
• D. Filtration of red blood cells

Answer: (A)

Detoxification is a major job the liver does besides making bile. It continually processes and neutralizes harmful substances that enter the body or are produced inside it. Liver cells use enzymes to modify drugs and alcohol, making them easier to eliminate from the body. It also converts toxic waste like ammonia into urea, which the kidneys then excrete. Through these actions, the liver helps keep the bloodstream clear of poisons and maintains chemical balance in the body.

While the liver does contribute to other tasks in the body, such as producing certain plasma proteins, storing some nutrients, and housing cells that filter bacteria and aged cells, those roles are not its defining functions in the same way detoxification is.
