Breathing rate and the volume of air inside the lungs are related. We have what's called tidal volume that is the amount of air in one inhalation and exhalation when at rest, and we have vital capacity which is how much air is forcibly moved in and out of the lings in one inhalation and exhalation. The lungs expand and become bigger during this process with the help of additional muscles besides just the diaphragm. When your breathing rate increases the size of your lungs do too.

During expiration, it relaxes,i.e., the pulmonary volume decreases.

What happens in the lungs when you breath in air?
The air travels down into your lungs and into small air pockets called capillary The air is then transferred through the capillary as they are really thin. Oxygen from the air is taken in and used around the body and the excess carbon dioxide is breathed back out as t is not needed in the body. You lungs also get bigger as you take a breathe, this creates a larger surface area as the chest goes out. The chest gets smaller as you breathe out as your lungs relax.
