The lifespan of Red Blood Cells is __ days:

🧠 Explanation:

Red blood cells, with a lifespan of about 120 days, are vital for oxygen transport in the body. Produced in bone marrow, they carry hemoglobin, delivering oxygen to tissues and removing carbon dioxide. After 120 days, they’re broken down in the spleen and liver, with components recycled. This cycle ensures efficient oxygen delivery, supporting bodily functions. Understanding their lifespan is key in medical fields like hematology, aiding diagnoses of conditions like anemia. Their consistent turnover reflects the body’s remarkable ability to maintain balance, sustaining life through a continuous process of renewal and waste management.
