^How the body protects itself: First Line of Defense:
" Mechanical - examples include the skin, which acts as a
barrier, and the sticky mucus on mucous membranes, which serves
to trap pathogens.
Physical - examples include coughing, sneezing, vomiting, and
diarrhea. Although not pleasant, these serve to expel pathogens
that have gotten past the initial barriers.
Chemical - examples include tears, saliva, and perspiration.
These have a slightly acidic nature that deters pathogens from
entering the body while also washing them away. In addition,
stomach acids and enzymes serve to kill germs."
Notice how these methods used by the body are exactly the same
type of methods we use to protect and clean things that we own.
Stick a drop cloth on it, or use wax (traps dust making it
easier to wipe away. Physical - sweeping the floor. Chemical,
Pinesol, bleach, soap and water.^
