What is the term for red blood cells?

• A. Erythrocyte
• B. Leukocyte
• C. Thrombocyte
• D. Plasma

Answer: (A)

The term for red blood cells is erythrocyte. This name comes from Greek roots: erythros meaning red and kytos meaning cell. Erythrocytes are the blood cells responsible for carrying oxygen to tissues via hemoglobin, which is why they’re specialized for gas transport. Their career is supported by a biconcave shape that increases surface area for efficient diffusion, and in mammals they’re mature without nuclei to maximize hemoglobin content. They’re produced in the bone marrow through erythropoiesis and are regulated by erythropoietin in response to oxygen needs. In contrast, leukocytes are white blood cells, thrombocytes are platelets, and plasma is the liquid component of blood, not a cell.
