What happens to RBC?

Red blood cells (RBCs) are responsible for transporting oxygen from the lungs to tissues and carbon dioxide from tissues back to the lungs. They have a lifespan of about 120 days, after which they are typically broken down in the spleen or liver. The hemoglobin in RBCs is recycled, with iron being reused for new RBC production in the bone marrow. If there are issues such as hemolysis or a decreased production rate, it can lead to anemia or other blood disorders.
