nonspecific defenses to pathogens, typically called the first and second line of defense
the body's defense to specific pathogens, includes humoral immunity and cell-mediated immunity (creates memory cells)
the bodies response to pathogens within body fluids with the use of specific antibodies
A "Y shaped" protein molecule evoked in response to a foreign antigen, It interacts specifically with that antigen.
immunity that develops as a result of natural or deliberate exposure to an antigen
overreaction of the immune system to a harmless antigen
Immune response to pathogens within infected body cells. Involves Killer-T cells
Innate immune response raising body temperature to speeds up the body's immune system and slows down the pathogen
chemical released by mast cells that increase the flow of blood and fluids to an infected area during the inflammatory response
disruption in homeostasis caused by a pathogen
nonspecific defense to tissue damage caused by injury or infection.
Redness, Pain, Swelling, and Heat
nonspecific response to viral infections, disrupt viral protein production
temporary immunity from specific pathogens, either by being given antibodies or antibiotics
an organism that transports disease "carrier"
disease that can be transmitted from one species to another
injection of a weakened or dead pathogen that causes the body to produce antibodies and memory cells
A preparation of weakened or dead pathogens that will cause an immune response and provide immunity
An organism that harbors or nourishes another organism
Used to treat bacterial or parasitic infections
Prokaryotic cells that multiply quickly and release chemicals that disrupt homeostasis
a small infectious agent (noncellular) that replicates only inside the living cells of other organisms
Eukaryotic cells that disrupt homeostasis
White blood cells
Helper T cell
Involved in both cellular and humoral immunity, relays the antigen info to B cells and killer T cells
"big eater" phagocyte that engulfs pathogens and displays their antigens on its surface
cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells
