The primary lymphocyte is a type of white blood cell that plays a crucial role in the immune system, primarily responsible for adaptive immunity. The two main types of lymphocytes are B cells, which produce antibodies, and T cells, which help regulate immune responses and directly attack infected cells. These cells originate from hematopoietic stem cells in the bone marrow and mature in various sites, such as the thymus for T cells and the bone marrow for B cells. Together, they are essential for recognizing and responding to specific pathogens.
