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