lymphocyte

Lymphocytes are a type of white blood cell that plays a crucial role in your immune system. They help identify and remember germs like bacteria, viruses, and other pathogens, enabling your body to defend itself against infections. There are two main types: B cells, which produce antibodies to attack invaders, and T cells, which destroy infected cells and coordinate immune responses. Lymphocytes are primarily found in the blood and lymphatic tissues, such as lymph nodes and the spleen. They are essential for maintaining your body's ability to fight off illness and keep you healthy.
