respiratory system Flashcards
3 main functions
gas exchange
deliver air from atmosphere into lungs
inspiration
movement of air from outside into lungs
respiritory rate
amount of breaths per minute
expiration
movement of air from lungs to outside
residual volume
amount of air left into the lungs
ventialtion
amount of air breathed in and out per minute
TVXRR
ventilation is abke to increase until max level
tidal volume (TV)
tv is increased until submax
diaphgram breathing in
when we breath in the diaphragm contracts allowing the lungs to expand
diaphragm breathing out
when we breath out the diaphragm relaxes
pulmonary diffusiion
gas exchange @ the lungs
gas exchange
when oxygen moves into blood carbon dioxide moves into lungs
oxygen deficit
oxygen demanded by the activity is greater than the oxygen being supplied by the body.
steady state
when o2 supply equals o2 demand
EPOC
amount of oxygen consumed during the recovery from exercise that is above resting levels
when you go off to the bench, breathing doesn go down straight away
respiritory control centre
monitors oxygen and carbon dioxide levels in the bloodstream and adjusts breathing rates to maintain homeostasis.
