Which organ is primarily responsible for detoxifying harmful substances in the body?

The liver is the primary organ responsible for detoxifying harmful substances in the body. It performs this critical function through a series of complex biochemical pathways that involve the conversion of fat-soluble toxins into water-soluble compounds, making them easier for the body to excrete. This detoxification process helps to eliminate drugs, alcohol, and metabolic waste products, reducing their toxicity and preventing damage to other organs and tissues.

The liver also plays a key role in metabolism, breaking down nutrients and synthesizing proteins necessary for various bodily functions. Its dual role as both a metabolic hub and a detoxifier highlights why it is considered the body's primary filter for harmful substances.
