The anatomical structure responsible for filtering toxins from blood is the liver. The liver performs essential functions, including detoxification, metabolism, and the regulation of biochemical processes necessary for maintaining overall health. Through its complex vascular structure and specialized cells, the liver filters out waste products, drugs, and harmful substances, converting them into less toxic forms for elimination from the body. Additionally, the liver plays a vital role in metabolizing nutrients and storing energy, thus contributing to various physiological functions and the maintenance of homeostasis.
