The human organ responsible for detoxifying harmful substances is the liver. It plays a crucial role in filtering blood, metabolizing drugs, and clearing toxins from the body. The liver also produces bile, which aids in digestion and the absorption of fats. Additionally, it stores essential nutrients and vitamins, regulating blood sugar levels, and producing important proteins for blood clotting. Due to its central role in metabolic processes, maintaining liver health is vital for overall well-being. Factors like alcohol consumption, poor diet, and infections can impair liver function, leading to serious health issues.
