skin and glads defensive roles Correct Ans-protects more vulnerable areas underneath

various glands in skin secrete sweat, which has antibacterial & anti-fungal properties
stressors that breach skin and glands Correct Ans-lacerations, abrasions, punctures
membranes/glands of body openings (eyes) defense Correct Ans-tears: blinking causes
lacrimal glands to spread tears over eyes & the tears drain into lacrimal ducts, washing the
eye regularly
eyelashes

happens to some degree to almost everyone as they age

stressors of respiratory system Correct Ans-cigarette smoking changes bronchial cells - no
more cilia
cough reflex suppression such as in head injury or stroke
gastrointestinal system defenses Correct Ans-saliva contains protective enzymes
stomach - HCl destroys most microbes
gag reflex / vomiting gets rid of injurious agents such as harmful bacteria
bowels - defecation gets rid of injurious agents such as harmful bacteria
stressors of the gastrointestinal system Correct Ans-Sjorgen's system - dries up saliva, so
less protection in mouth
anything that changes the bowel flora can leave us open to invading microbes (antibiotics)

second line of defense in one word Correct Ans-inflammation
manifestations of inflammation Correct Ans-SHED - swelling, heat, erythema (redness) and
pain
example of normal inflammation Correct Ans-skin is breached (first line of defense) by a
cut or laceration -> area becomes red and sore as normal inflammation takes place ->
immediately, certain processes take place during inflammation which result in clot formation
to stop bleeding -> fibrin components are weaved together through to form a scab to seal the
breach -> eventually it becomes less painful as it heals
normal inflammation process Correct Ans-usually acute and short lived
