Question 1

How do the reticuloendothelial cells compare to white blood cells as a defense against infection?

Accepted Answer

A)  Only white blood cells play a role in the body's defense against infection. 
B)  There is no comparison between these two types of cells; reticuloendothelial cells are in the lymphatic system and the white blood cells are part of the circulatory system. 
C)  Reticuloendothelial cells (macrophages) lining the spleen remove microorganisms from the blood and destroy them by phagocytosis in a fashion similar to that of white blood cells. 
D)  Reticuloendothelial cells (macrophages) lining the spleen prevent microorganisms from entering the blood in a similar fashion as do white blood cells, thus preventing infection.
