What is the primary function of the liver in metabolism?

The primary function of the liver in metabolism is detoxification. The liver plays a crucial role in processing and eliminating toxins and harmful substances from the blood, which contributes significantly to maintaining metabolic balance. It breaks down drugs, alcohol, and other waste products, converting them into less harmful substances that can be excreted through urine or bile.

In addition to detoxification, the liver also regulates the levels of various metabolites in the body, such as glucose, protein, and fat, contributing to overall metabolic homeostasis. While the liver does have roles in fat storage, insulin production, and other metabolic functions, detoxification is its most essential task, as it helps to protect the body from the accumulation of harmful substances that could disrupt various metabolic processes.
