Write short note on respiratory volumes.

Explanation

Tidal Volume (TV) Tidal volume is the amount of air inspired or expired with each normal breath . It is approximately 500 mL . , i.e., a normal human adult can inspire or expire approximately 6000 to 8000 mL of air per minute . During vigorous exercise , the tidal volume is about 4- 10 times higher
Inspiratory Reserve volume (IRV) Additional volume of air a person can inspire by forceful inspiration is called Inspiratory Reserve Volume . The normal value is 2500- 3000 mL .
Expiratory Reserve Volume (ERV) Additional volume of air a person can forcefully exhale by forceful expiration is called Expiratory Reserve Volume . The normal value is 1000- 1100 mL .
Residual Volume (RV) The volume of air remaining in the lungs after a forceful expiration . It is approximately 1100-1200 mL .
