9046996615Inflammatory ResponseVasodilation, phagocytosis, and increase in body temperature0
9046996616Histamineschemical signals that trigger vasodilation, increasing blood supply to area and cause inflammation.1
9046996617PhagocytesWhite blood cells that engulf invading pathogens e.g., neutrophils, macrophages2
9046996618Chemokineschemical signals secreted by blood vessel cells that attract more white blood cells (phagocytes) to the area3
9046996619Specific immunityB and T cells; humoral and cell-mediated response4
9046996620LymphocyteWhite blood cell5
9046996621B CellsHumoral response by producing antibodies; activated by T cells or free antigens6
9046996622T CellsCell-mediated response, stimulating by APCs (antigen presenting cells)7
9046996623Helper T CellSet off an alarm to the immune system that pathogens have broken through the body's line of defense; binds to class II MHC8
9046996624Cytotoxic T CellKills body cells that have been infected with pathogens; stimulated by antigens and helper T-cells9
9046996625MacrophagesAPC that engulfs large numbers of pathogens; presents antigen to activate T cells10
9046996630Memory CellsResponsible for lifelong immunity by storing copy B and T cells to more quickly fight secondary infection11
9046996631AntibodyY-shaped protein with variable antigen bind region; slows pathogens to facilitate destruction12
9046996632AntigenIdentifying marker on the outside of a pathogen13
9046996633Passive ImmunityTemporary immunity where antibodies are transferred from another animal ex: mother transfers some of her antibodies to her nursing child14
9046996634HIVA retrovirus that attacks helper T cells15
9046996635Autoimmune diseaseA mistake in the immune system where the body does not properly distinguish self from nonself16
9046996636AllergyHypersensitive immune response to certain substances that causes that release of histamine17
9046996637Dendritic CellsDuring primary immune responses, the principle antigen-presenting cells in the lymph nodes18
9046996638Innate ImmunityGeneral, non-specific protection to the body, including the skin (barrier), gastric acid, phagocytes, and lysozyme.19
9046996640Natural Killer CellsA type of white blood cell that can kill tumor cells and virus-infected cells; an important component of innate immunity.20
9046996641Mast CellsCells that release chemicals (such as histamine) that promote inflammation.21
9046996642Humoral ResponseThe branch of acquired immunity that involves the activation of B cells and that leads to the production of antibodies, which defend against bacteria and viruses in body fluids.22
9046996643Cell-mediated ResponseThe branch of acquired immunity that involves the activation of cytotoxic T cells, which defend against infected cells.23
