non specific defenses
innate immunity |
defenses present at birth. no memory response. includes first and second line defenses |
adaptive immunity |
third line defense. not born with it it changes with experience (has memory) |
|
|
first line defences: physical
skin |
closely packed cells, shedding, dryness (at risk when surface is broken) |
mucous membrane |
cilia pushes microbes out, secrete mucous |
lacrimal apparatus |
eye protection, tears wash surface of eyes, act as wind shield wipers |
saliva |
dilute and wash teeth and oral membranes |
other physical factors |
epiglottis- protects respiratory tract from saliva/ microbes from mouth |
|
|
first line of defense: chemical
sebum |
oily substance from sebaceous glands |
perspiration |
eliminates wastes and flushes microbes from skin |
earwax |
secretes rich fatty acids |
saliva |
lysosome, urea, uric acid, IgA |
gastric juice |
protection from food particles |
