27
Q

3 layers of defense and how they work

A
  1. skin (protective outer layer)
  2. Enzymes (decreases or increase ph level to destroy microorganism, secretion of sweat)
  3. temperature (elevation of body temp create inhospitable environment for many pathogen)
28
Q

define antigen

A

foreign substance capable of triggering immune response

29
Q

antibodies

A

substance produced by body to destroy or weaken specific antigens

30
Q

what is humoral immunity

A

body does antigen analysis (size, shapes, foreign) and release specific antibody to destroy or weaken antigen

31
Q

what is cell mediated immunity

A

formation of population lymphocytes that attack and kill invader (viruses, fungi, parasites, some bacteria)

lymph nodes
glands
