| immunology (im-yŭ-NOL-ŏ-jē) | immun/o/logy study of disorders of the immune system |
| phagocytosis (făg-ō-sī-TŌ-sĭs) | phag/o/cyt/osis Process where some white blood cells engulf invading microorganisms |
| acute inflammation (ă-KŪT in-flă-MĀ-shŏn) | Inflammation occurring for a limited time period, rapidly developing |
| afferent lymphatic vessels (AF-ĕ-rĕnt lim-FAT-ik VES-ĕls) | vessels that lead into a lymph node |
| allergen (AL-ĕr-jĕn) | Substance capable of producing an allergic (hypersensitivity) reaction |

| allergy (AL-ĕr-jē) | inflammatory response due to a hypersensitivity to a substance |
| antibody (ANT-i-bod-ē) | antigen-specific protein secreted by plasma cells, immunoglobulin |
| antigen (ANT-i-jĕn) | molecule recognized by the receptors of b and t lymphocytes |
| apoptosis (ap-ŏp-TŌ-sĭs) | Programmed cell death to regulate cell population, some cancers disrupt apoptosis |
| autoimmune disease (OT-ō-im-yūn diz-ĒZ) | aut/o/immun/e disease A disease caused by the inability for the body to distinguish its own (self) cells from foreign substances, producing antibodies that attacks its own tissues |
| bone marrow (bōn MAR-ō) | tissue found inside bones, the site of all blood cell differentiation and mautration of b lymphocytes |
| chronic inflammation (KRON-ĭk in-flă-MĀ-shŏn) | Inflammation occurring for long periods of time |

| graft-versus-host disease (GVHD) | In bone marrow transplants, occurs when the transplanted cells mount an immune response against the recipient |
| histamine (HIS-tă-mēn) | Vasoactive mediator in granules of mast cells Primary cause of allergies and anaphylactic shock |
| immunity (im-Ū-nĭt-ē) | Post infection, memory cells remain in the body providing an immune response to the same pathogen. This protects us from getting sick by the same pathogen |
