What causes the feeling of a “full breath” of air?

Question

There are times where I take a whole lungful of air, and yet feel like the breath is somehow incomplete, unsatisfying. Other times I may take only a half breath, except there is a point where my lungs will feel as if they are fully expanded to a “satisfying” level, as if I got exactly the breath my body needed in that moment. Is there a known cause of this feeling?

Happens a lot when I yawn. I will yawn to this point where my lungs get this last little extra bit of breath that feels wholly satisfying.
