The video explains the liver's essential functions, including blood filtration, detoxification, immune response, blood clotting, digestion, and blood glucose regulation. It highlights the liver's structure, its role in filtering blood and removing toxins, the immune function of Cooper cells, the production of clotting factors, bile production for digestion, and the regulation of blood glucose levels in collaboration with the pancreas.
