Where are all RED BLOOD CELLS recycled?
A
thymus
B
bone marrow
C
tonsils
D
spleen
Explanation: 

Detailed explanation-1: -All the other cellular proteins are either recycled or eliminated. Historically, this process was thought to occur exclusively in the spleen, but recent studies have shown that it occurs in the bone marrow.

Detailed explanation-2: -The embryonal spleen derives from primitive mesenchyme. During the fifth fetal month certain fixed mesenchymal cells in the spleen give rise to so-called hemocytoblasts which in turn produce erythroblasts. 9 At this time the production of red cells is a normal function of the spleen.

Detailed explanation-3: -Often, the spleen is referred to as the “graveyard of RBCs”. Also, the spleen stores RBCs by eliminating the dead and damaged cells. About 20-25% of the red blood cells are stored in the spleen. The spleen also stores other blood cells such as WBCs and platelets.

Detailed explanation-4: -Your spleen is involved in your body’s immune response, and in recycling old blood cells.
