What organ filters blood to remove amino acids and neutralize some harmful toxins?

The liver plays a crucial role in filtering blood and has several vital functions in metabolism and detoxification. It processes nutrients absorbed from the digestive system, including amino acids, which can be converted into various substances needed by the body or stored for future use. Additionally, the liver detoxifies harmful substances, such as drugs and toxins, transforming them into less harmful compounds or facilitating their elimination from the body. This dual function of processing nutrients and neutralizing toxins highlights why the liver is often referred to as a central organ for metabolic regulation and detoxification in human physiology.
