daptive immunity - the ability to recognize and remember specific antigens and mount an attack on them innate immunity - Nonspecific immunity that is responsible for natural immunity to a vast array of environmental threats and microorganisms 7 innate defenses - Epithelial barriers, mucociliary clearance, phagocytes, dentritic cells, innate lymphoid cells, mast cells, complement proteins 7 major cellular components of immune system - Monocytes, macrophages, lymphocytes, neutrophils, basophils, eosinophils, and mast cells mononuclear phagocytes - Play central role in the immune response tissue phagocytes - Derived from blood monocytes and participated antigen processing and the secretion of mediators vital to initiating specific immune responses Lymphocytes - Responsible for the initial recognition and binding to specific antigens 2 lymphocyte types and function - The two types of white blood cells that are part of the body's immune system: B lymphocytes form in the bone marrow and release antibodies that fight bacterial infections (antibody response); T lymphocytes form in the thymus and other lymphatic tissue and attack cancer cells, viruses, and foreign substances (immune response) Eosinophils - Found in inflammatory sites or at sites of immunoreactivity and play a crucial role in the host defense against parasites mast cells - Found in areas such as the skin, conjunctiva, respiratory, and G.I. tract and are responsible for immediate hypersensitivity to a pathogen
