What distinguishes the function of leukocytes from that of erythrocytes?

• A. Leukocytes carry oxygen; erythrocytes fight infection
• B. Leukocytes are involved in immunity; erythrocytes are designed for oxygen transport
• C. Leukocytes aid in clotting; erythrocytes do not
• D. Leukocytes are only present during inflammation; erythrocytes are always present

Answer: (B)

Leukocytes, or white blood cells, play a critical role in the body's immune system, helping to identify and combat pathogens such as bacteria, viruses, and other foreign invaders. Their primary function is to protect the body against infections and to mediate immune responses. This includes activities such as phagocytosis (engulfing and digesting microorganisms), producing antibodies, and releasing chemicals that mediate inflammation and other immune reactions. On the other hand, erythrocytes, or red blood cells, are specialized for transporting oxygen from the lungs to the tissues and returning carbon dioxide from the tissues back to the lungs. Their structure, which includes a high concentration of hemoglobin, is specifically designed for maximizing oxygen uptake and delivery throughout the body. Thus, the distinction between the roles of leukocytes and erythrocytes lies in their primary functions: leukocytes are integral to the immune response, while erythrocytes are crucial for respiratory gas transport. This differentiation highlights the specialized nature of these two types of cells in maintaining homeostasis and responding to physiological challenges.
