Expiratory reserve volume (ERV):

The amount of additional air that can be breathed out after normal expiration. (At the end of a normal breath, the lungs contain the residual volume plus the expiratory reserve volume, or around 2.4 liters. If one then goes on and exhales as much as possible, only the residual volume (RV) of 1.2 liters remains). The maximum volume of air that can be expired in addition to the normally expired air.

This is what leaves:
Initial reaction/shock/pain/ERV.

What is left, is a hollow space.
A hollow space/RV.
The kind you hold in your throat.
