diffusion

the movent of gas molecules from an area of high concentration or partial pressure to an area of low concentration or partial pressure

1 of 13

gaseous exchange

the movement of o2 from the air into the blood and co2 from the blood into the air

2 of 13

tidal volume

volume of air breathed in or out per breath

3 of 13

inspiratory reserve volume

volume of air that can be forcely inspired after a normal breath

4 of 13

expiratory reserve volume

volume of air that can be forcibly expired after a normal breath

5 of 13

residual volume

the amount of air that remains in the lungs after maximal expiration

6 of 13

spirometer

a device that is used to measure the volume of air inspired and exoired by the lungs

7 of 13

partial pressure

the pressure exerted by an individual gas when it exists within a mixture of gases

8 of 13

diffusion

the movement of gas molecules from an area of high concentration to an area of low concentration

9 of 13

concentration/diffusion gradient

often reffered to as the concentration gradient. it explains how gases flow from an area of high concentration to an area of lowconcentration. the steeper the gradient (difference between concentration levels at high and low areas) the faster diffusi

proprioceptors

sensory receptors found in muscles and joints that provide information to the central nervous system about position and movement

11 of 13

cilia

cilia are microscopic hair-like projections that help to sweep awayfluids and particles

12 of 13

copd

a chronic and debilitating disease and is the name for a collection of diseases such as emphysema. the main cause of emphysema is smoking. it is a long-term progressive disease of the lungs that causes shortness of breath
