define lung volume and air pressure. then describe how changes in lung volume and air pressure within the lungs allow inspiration and expiration to occur.

do it on your own words don't copy and paste from another cite

Lung: one of the usually paired compound saccular thoracic organs that constitute the basic respiratory organs of an air-breathing vertebrate

Volume: is the space in a object... (Is that correct?)

Air Pressure: atmospheric pressure is closely approximated by the hydrostatic pressure caused by the weight of air above the measurement point.

Idk air pressure so I copied it from google. Sorry.
