Which blood cells help in fighting infections in the human body?
White blood cells
White blood cells (WBCs or leukocytes) form the body's defence system. Neutrophils and monocytes (macrophages) engulf and destroy germs by phagocytosis, and lymphocytes produce antibodies against specific infections.
Red blood cells contain haemoglobin and carry oxygen; platelets help in blood clotting; plasma is the liquid part of blood that transports nutrients, hormones and wastes and is not a cell at all.
Hence, the answer is White blood cells.
