Which term is used to refer to white blood cells?

The term used to refer to white blood cells is "leukocyte." Leukocytes play a crucial role in the immune system, helping the body to fight infections and other diseases. Unlike red blood cells (erythrocytes), which carry oxygen throughout the body, or platelets (thrombocytes), which are involved in blood clotting, leukocytes are specifically involved in immune responses. They are classified into various types, including lymphocytes, neutrophils, and monocytes, each serving different functions in the defense against pathogens. The significance of leukocytes in maintaining health and combating infections underscores their vital role in the body's overall defense mechanism.
