18
Q

20
Q

Function of basophils

A

alert the body of invasion

21
Q

Function of eosinophils

A

large, long-living phagocytes that defend against multicellular invaders

22
Q

Function of Helper T Cells

A

helps the body fight infections by producing antibodies and other chemicals

23
Q

Function of Killer T Cells

A

destroy cells that are infected with a virus or pathogen and tumor cells

24
Q

Function of Suppressor T Cells

A

stop or “suppress” the other T cells when the battle is over

25
Function of Memory T Cells
remain in the blood on alert in case the invader attacks again
26
Function of B Lymphocytes
produces antibodies aka B cells
27
Proteins on the surface of bacteria, viruses, and fungi
Antigens
28
Adaptive immunity
encounters infection or has an immunization
29
Naturally acquired active immunity
exposed and builds immunity without an immunization
30
Artificially acquired active immunity
exposed and builds immunity due to a vaccine
31
Naturally acquired passive immunity
happens during pregnancy; antibodies move from the mother's bloodstream to the fetus also occurs during breast feeding
32
Artificially acquired passive immunity
immunization given in recent outbreaks or emergency situations
