Which term refers to red blood cells?

• A. ERYTHROCYTES
• B. LEUKOCYTES
• C. PLASMA
• D. THROMBOCYTES

Answer: (A)

The term for red blood cells is erythrocytes. Erythrocytes are responsible for carrying oxygen from the lungs to tissues throughout the body using hemoglobin, and they also help transport a portion of carbon dioxide back to the lungs for exhalation. They are the most abundant formed elements in blood, and their biconcave shape increases the surface area available for gas exchange. In humans, mature erythrocytes lack a nucleus, which frees space for more hemoglobin and enhances oxygen-carrying capacity. The other terms refer to different blood components: leukocytes are white blood cells involved in immune defense, plasma is the liquid component that carries cells and proteins, and thrombocytes (platelets) play a key role in blood clotting.
