Liver vs. Lungs & Kidneys: Who Filters Blood?

The liver does not remove carbon dioxide and water from blood. The primary function of the liver is to detoxify the blood, produce bile, store glycogen, and metabolize nutrients. The lungs, on the other hand, are responsible for removing carbon dioxide and adding oxygen to the blood through the process of respiration. The kidneys are responsible for removing water and waste products from the blood.
