The liver is the organ primarily responsible for detoxification in the body. It plays a crucial role in metabolizing nutrients and filtering toxins from the bloodstream. The liver processes chemicals, breaking down drugs and alcohol and converting them into less harmful substances that can be excreted from the body. It also produces bile, which helps in the digestion and absorption of fats. Additionally, the liver stores vitamins and minerals and plays a significant role in regulating blood sugar levels, making it vital for overall health and homeostasis.
