The organ primarily responsible for filtering toxins from the blood is the liver. This vital organ performs numerous functions essential for maintaining overall health, including detoxifying harmful substances, producing bile for digestion, and synthesizing proteins necessary for blood clotting and immune response. The liver processes nutrients from the food we eat and plays a critical role in metabolism. It has the remarkable ability to regenerate, which allows it to recover from damage due to factors such as alcohol consumption, medication, and certain diseases. Maintaining liver health is crucial for overall well-being.
