This is a PV concept from TBR CBT4 that I am confused about.
Let's say you are at some depth in the ocean where the external pressure of the surrounding water is much greater than the pressure inside your lungs. If you hold your breath, why would the volume inside your lungs then decrease?
The explanation given is that the external pressure of the surrounding water causes the volume in the lungs to decrease. Doesn't holding one's breath mean maintaining a constant volume?
