Expiratory Capacity (EC) -

Total volume of air a person can expire after a normal inspiration

- wherein

This includes tidal volume and expiratory reserve volume (TV+ERV)

 

 

 

Expiratory Capacity =TV+ERV

                                =500 mL+1000mL

                                =1500\; mL


Option 1)

1500\; mL

Option 2)

1700\: mL

Option 3)
