Which blood cells are commonly referred to as the 'soldiers' of the human body due to their role in fighting infections?

💡 Solution & Explanation

Leukocytes, or white blood cells, are termed the soldiers of the human body because they actively defend it against infectious diseases and foreign invaders through phagocytosis and antibody production. Erythrocytes are red blood cells responsible for oxygen transport, while thrombocytes function in blood clotting. These cells originate primarily from multipotent hematopoietic stem cells in the bone marrow. An abnormal increase in leukocyte count often indicates an ongoing infection or inflammation.
