removal of aged and damaged red blood cells from the blood

Explanation:

Spleen is an organ found in vertebrates and it is located in the upper part of the abdomen that act majorly to filter blood. It recognizes and removes old, malformed, or damaged and aged red blood cells. When blood flows into the spleen, the spleen performs "quality control"; the red blood cells must pass through a maze of narrow passages.

The bone marrow is a spongy tissue that produced red blood cells and this perform similar function as the spleen except that it cannot remove aged and damaged red blood cells from the blood this is because it does not have the ability to remove age and damage red blood cells due to inability to support the immune system.

The spleen help remove age and damage red blood cells thereby boosting the immune system in fighting against infections ,preventing blood clot .
