Kupffer cells reside in the liver and perform which function?

Explanation:
Kupffer cells are liver-resident macrophages that line the hepatic sinusoids and actively clean blood as it flows through the liver. Their primary function is phagocytosis of bacteria, debris, and old or damaged red blood cells, helping to keep the portal circulation free of pathogens and waste. They also play a role in antigen processing and cytokine signaling to coordinate immune responses in the liver. This activity distinguishes them from hepatocytes, which handle metabolism and bile production; Langerhans cells, which are skin dendritic cells for antigen presentation; and enterocytes, which are intestinal absorptive cells.
