B cells or B lymphocytes are produced and matured in the red bone marrow and secrete antibodies. B cells have receptors for recognition of antigens and activate antibody response. They act against extracellular pathogens and involved in the humoral immune response. T cells or T lymphocytes are produced in the bone marrow and matured in the thymus. T cells play a crucial function in the cell-mediated immunity. T cells act against intracellular pathogens (for example, viruses) or antigens and they activate the cell-mediated immune response. T cells are classified into three classes (cytotoxic T cells, helper T cells, and regulatory T cells) according to surface molecules and functions.

Question 1 Nursing. Innate lymphoid cells reside primarily in tissues such as the lungs, the lining of the gastrointestinal tract, and the skin, because these sites represent the major routes of entry of pathogens into the body. Several different subsets of innate lymphoid cells exist, and each is specialized to respond to a category of pathogen (e.g., viruses, extracellular bacteria, helminthic parasites, etc). a) True b) False
