Which component of blood is primarily responsible for fighting infection?

Explanation:
White blood cells are the defense troops of the blood. They patrol the body, recognize foreign invaders, and respond by engulfing pathogens or producing antibodies and coordinating the immune response. This makes them the primary fighters against infection. Red blood cells mainly carry oxygen, platelets help form clots to stop bleeding, and plasma is the liquid that transports nutrients, hormones, and immune proteins; while antibodies circulate in plasma, the direct battle against infection is carried out by the white blood cells themselves.
