Hemolytic anemia may involve either intravascular hemolysis, in which red blood cells are destroyed within the circulation, or extravascular hemolysis, in which the cells are destroyed in the liver or spleen.

bone marrow
Erythrocytes are produced in the bone marrow and sent into the circulation. At the end of their lifecycle, they are destroyed by macrophages, and their components are recycled.

How the RBC destruction occurs?

How does RBC get destroyed?

Human red blood cells (RBCs) are normally phagocytized by macrophages of splenic and hepatic sinusoids at 120 days of age. The destruction of RBCs is ultimately controlled by antagonist effects of phosphatidylserine (PS) and CD47 on the phagocytic activity of macrophages.

Where are the RBC destroyed Mcq?

Where are the RBCs destroyed? Explanation: The liver is responsible for detoxifying the body. Just like kidney filters blood and removes all the waste, the liver detoxifies the blood and ensures that the dead and dying cells are destroyed and removed. 9.

Why are RBCs destroyed after 120 days?

These cells get trapped and engulfed by splenic macrophages. The average life of a normal human red cell is found to be 120 +/- 20 days. These rigid red cells are unable to deform enough to squeeze through the physical barriers in the spleen sinusoids, so are destroyed; just like spherocytes.
