Question

Phagocytic endothelial cells are

• A. Monocytes
• B. Kupffer's cells
• C. Lymphocytes
• D. Plasma cells

Answer 1

The correct option is B Kupffer's cells

• A cell that engulfs and ingest microbes, toxic substances and foreign particles are called phagocytic cells.
  
• The cells that line the interior region of blood vessels and lymphatic vessels are known as endothelial cells.
  
• Kupffer cells are also known as stellate macrophages.
  
• They are specialized macrophages which are found in the liver, lining the walls of the sinusoids.
• They are a part of the mononuclear phagocytic system.
• These cells constitute about 80-90% of the macrophages present in the body.
  
• They help in phagocytosis and defend against viral and bacterial infections.
• So, the correct answer is 'Kupffer's cells'.
