the movement of gas molecules from an area of high concentration or partial pressure to an area of low concentration or partial pressure
1 of 12
gaseous exchange
the movement of oxygen from the air into the blood, and carbon dioxide from the blood into the air
2 of 12
tidal volume
volume of air breathed in or out per breath
3 of 12
inspiratory reserve volume (IRV)
volume of air that can be forcibly inspired after a normal breathe
4 of 12
expiratory reserve volume (ERV)
volume of air that can be forcibly expired after a normal breathe
5 of 12
residual volume
the amount of air that remains in the lungs after maximal expiration
6 of 12
spirometer
a device that is used to measurlthe volume of air inspired and expired by the lungs
7 of 12
partial pressure
the pressure exerted by an individual gas when it exists within a mixture of gases
8 of 12
concentration gradient
explains how gases flow from an area of high concentration to an area of low concentration . the steeper this gradient, the faster diffusion occurs
9 of 12
proprioceptors
sensory receptors found in muscles and joints that provide information to the central nervous system about position and movement

cilla
microscopic hair-like projections that help to sweep away fluids and particles
