2) inspiratory reserve volume (Irv) it is the additional volume of a person may inspired by a forcefully Pareshan it is appropriate to 2500 ml to 3000 ml
3)expiratory reserve volume (e r v) it is the additional volume of a person can expired by possible expiration it is appropriate average 1000 ml 1100ml
4)vital capacity VC maximum volume of air a person can break in after a force desperation it is total of ERV+ TV+ Irv it is the maximum volume of a a a person can breathe out after forced inspiration
5)total lung capacity total volume of air accommodate in the lungs at the end of the fourth inspiration is called as total lung capacity
TLC=RV+ERV+TV+IRV
6) expiratory capacity: it is the total volume of air a person can expire after a normal inspiration
EC=TV+ERV
