1 Answer

Answer :

(4) Spleen Explanation: Old, "worn out" RBCs are mostly broken down in the spleen. It is the organ that filters the blood, checks it for infection, and removes undesirable substances. RBCs are produced in the red bone marrow of bones. The average life span of erythrocytes is about 120 days.
