    Acquired immunity is associated with specificity and memory. T helper cells express CD4 and are restricted to recognizing antigen bound to MHC class II on antigen presenting cells. Natural killer cells destroy virus-infected and tumor cells. Monocytes and macrophages are the cells of the immune system that phagocytose and degrade antigens. Neutrophils have a bilobed nucleus and granulated cytoplasm that stains with eosin. Organ transplantation involves transplanting tissue from one person to another. IgA is found primarily in secretions such as saliva, tears, and mucus. Mast cells and basophils play an important role in allergic reactions. T cell development occurs in the thymus and maturation occurs in the lymph nodes. Type
