Breathing Flashcards
(11 cards)
conducting zone
bringing the air from the outside to the lungs
respiratory zone
doing gas exchange
inspiration, breathing muscles contract causing:
increase in volume causing decrease in pressure causing air to flow in
expiration, breathing muscles relax causing:
decrease in volume causing increase in pressure causing air to flow out
restrictive disorders
impaired inspiration
obstructive disorders
impaired expiration
compliance
volume change that occurs with a certain pressure change, how easy air can flow in/out
surface tension
causes more muscles to be needed to expand the lungs, lowers compliance
surfactants
lower surface tension
central receptors
strongest effect, only respond to increase in CO2
peripheral receptors
respond mainly to CO2, but also O2 and H+
