Final answer:
The liver removes bilirubin from the blood, which is used to manufacture bile and phagocytizes bacteria and worn-out red blood cells for breakdown and excretion.
Step-by-step explanation:
The liver also removes bilirubin from the blood and phagocytizes bacteria and worn-out red blood cells. The breakdown of hemoglobin in red blood cells produces bilirubin, which is a yellow pigment carried in the blood to the liver. The liver uses this bilirubin in the manufacture of bile, necessary for the digestion of dietary fats. Bilirubin is transformed into stercobilin in the intestines and eliminated in feces, providing its characteristic color. Worn-out red blood cells are phagocytized by macrophages in various organs, including the liver, where these cells are broken down and recycled or excreted as waste.
