decreases- ✅✅ When the volume of a given quantity of gas increases, its pressure
_________
enters- ✅✅When pressure within the lungs is lower than the atmospheric pressure, air
________the lungs
Intercostal muscles- ✅✅ controls the rib cage allows it to expand and raise rib cage

contractions
inhalation- ✅✅contraction of the diaphragm making it more flat increases volume and
decreases pressure of lungs
Exhalation- ✅✅ relaxation of intercostal muscles diaphragm relaxes and moves up
intercostal muscles move the ribs down causing volume in lungs to decrease and
pressure increases
Tidal volume- ✅✅ lung volume representing the normal volume of air during inhalation
and exhalation
Vital Capacity- ✅✅ The maximum amount of air that can be expired after a forceful
maximum inspiration
✅✅ additional air taken in above tidal inhalation
Inspired reserve volume-
Expired reserve volume-✅✅ additional air that can be forced out beyond regular tidal
exhalation
✅✅ normal breathing per minute
