What does the liver phagocytize?

Phagocytosis in the liver is carried out mainly by Kupffer cells, the resident macrophages in the hepatic sinusoids. These cells patrol portal blood and engulf bacteria and worn-out red blood cells, helping to clean the circulation and recycle components from old RBCs. This function is a hallmark of the liver’s role in the reticuloendothelial system. Fats are processed by hepatocytes and bile for digestion, not by phagocytosis. Hormones are removed from circulation primarily through enzymatic metabolism in the liver rather than by engulfment. Viruses can be cleared by immune responses, and macrophages may encounter them, but the classic phagocytic targets of the liver are bacteria and aged red blood cells.
