Which organ is responsible for making poisons harmless in the body?

The liver is the organ responsible for making poisons harmless in the body. It plays a crucial role in metabolism and detoxification. The liver processes various substances, including drugs, alcohol, and toxins, transforming them into less harmful compounds or facilitating their elimination from the body.

This detoxification process often involves converting fat-soluble substances into water-soluble forms, which can then be excreted through urine or bile. Additionally, the liver produces enzymes that aid in the breakdown and removal of these harmful substances. Given its central role in detoxification, the liver is often referred to as the body's primary detox organ.

While the kidneys also play a significant role in filtering waste products from the blood and excreting them through urine, they primarily focus on excretion rather than detoxification. The lungs facilitate gas exchange and do not detoxify poisons, while the heart is responsible for pumping blood and does not have a detoxifying function. Thus, the liver is correctly identified as the organ that makes poisons harmless in the body.
