lymphocytes

Lymphocytes are a type of white blood cell vital to the immune system. They help protect the body from infections by recognizing and attacking bacteria, viruses, and other harmful substances. There are two main types: B cells, which produce antibodies to neutralize invaders, and T cells, which directly attack infected cells and coordinate the immune response. Lymphocytes circulate throughout the bloodstream and lymphatic system, continually surveilling for threats. Their efficient functioning is essential for maintaining health and fighting off illnesses.
