Transient flora
Ans: microbes that reside on the skin surface and are easily
removed
Medical asepsis
Ans: Known as the "clean technique" - used to keep area as
clean as possible to reduce transmission
Surgical asepsis
Ans: Known as the "sterile technique" - used when you want
zero transmission of microorganisms, so everything is kept in a
sterile field.
Goal of asepsis?

-The microorganisms capable of causing infection
-Through effective hand washing many of these can be removed

Ans: Reservoir
-Where the organism is housed while it's waiting for an
opportunity to infect/ multiply
Explain the 3rd step of the chain of infection
Ans: Portal of Exit
-The most common portals of exit include the mucous
membranes (i.e., mouth, nose, vagina, rectum) or breaks in the
