Heya..!
here's your answer..
inhaling and exhaling i.e., inspiration and expiration respectively are PHYSICAL CHANGES.
inspiration and expiration is done by creating a pressure gradient between lungs and atmosphere.
this is aided by , diaphragm and intercostal muscles.
let's see what this pressure gradient means. [REMEMBER THAT AIR MOVES FROM HIGH PRESSURE AREA TO LOW PRESSURE AREA]
inspiration can occur when pressure is less in lungs when compared to atmosphere. To lower down the pressure in lungs, diaphragm becomes flat so that thoracis cavity increases in length
to exhale out, pressure in lungs should be more than the pressure.
to increase the pressure in lungs, diaphragm relax making it into convex so that thoracic cavity decreses in length.
HOPE THIS HELPS YOU ❤
