Which term refers to white blood cells that defend against disease?

White blood cells defend against disease; these cells are called leucocytes. They circulate in blood and tissues, responding to infection by attacking pathogens, producing antibodies, and coordinating the immune response. Different types carry out these roles in various ways, such as neutrophils that quickly engulf bacteria and lymphocytes that target specific invaders. This is distinct from red blood cells (erythrocytes), which carry oxygen; plasma, the fluid that transports nutrients and cells; and platelets, which help blood clot. In skincare practice, a healthy leucocyte response supports healing and helps prevent infection after treatments.
