The liver is the organ primarily responsible for detoxifying chemicals and metabolizing drugs in the human body. It performs essential functions, including the breakdown of substances that can be harmful to the body, such as alcohol and medications. The liver also produces bile, which is necessary for digestion, and plays a key role in regulating metabolic processes, including the storage of glucose and the synthesis of proteins. Its unique ability to regenerate allows it to recover from damage, making it a vital organ for maintaining overall health and homeostasis in the body.
