To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue. cells and T cells are the major types of lymphocytes and are derived from hematopoietic stem cells in the bone marrow.
