Which organ is primarily responsible for detoxifying the blood?

• A. The kidneys
• B. The liver
• C. The pancreas
• D. The spleen

Answer: (B)

The liver is the primary organ responsible for detoxifying the blood. It performs this critical function by metabolizing substances that can be potentially harmful, such as drugs, alcohol, and toxins, converting them into less harmful compounds that can be excreted from the body. The liver processes these substances through a series of chemical reactions, including phase I and phase II reactions, which make them water-soluble for easier elimination via bile or urine.

In addition to detoxification, the liver produces important proteins such as albumin and clotting factors, regulates blood sugar levels, and stores various nutrients. Its central role in metabolism and detoxification highlights its importance in maintaining overall health and homeostasis in the body. Other organs involved in detoxification processes, like the kidneys, play supportive roles, but the liver is the key organ for this function.
