Q

2 types of threats

A

Antigens

Cells that re not behaving normally

26
Q

Non-specific immunity

A

Attacks everything that looks unusual

27
Q

Phagocytes

A

Scavengers that engulf and digest antigens before they infect cells

28
Q

Natural Killer Cells

A

Attack and destroy infected (cancerous) cells

29
Q

Specific Immunity

A

Attack specific threats that have been encountered before

30
Q

2 types of specific immunity

A

Humoral

Cell- mediated

31
Q

Humoral Immunity

A

Detects previously encountered antigens while still in body fluids

32
Q

2 cells in humoral immunity

A

B lymphocytes

Memory B cells

33
Q

B lymphocytes

A

Produce antibodies to slow antigens so they can be consumed by phagocytes

34
Q

Memory B cells

A

Remember previously encountered antigens

35

Fights infected cells

Memory T cells
Helper T cells
Suppressor T cells

37
Q

Killer T cells

A

Directly attack problem cells

38
Q

Memory T cells

A

Remember attack and quickly respond if it attacks again

39
Q

Helper T cells

A

Signals B and T cells to produce rapidly

40
Q

Suppressor T cells

A

Stop production of B and T cells to bring body back to baseline

A

M: 85%
W: 81%

47
Q

Retrovirus

A

Enters host cell, RNA copies itself into DNA, DNA integrates into host DNA and host replicates viral RNA
