I believe you were talking about the intercoastal muscles and your diaphragm movement. As for things like going through your nasal cavity, I shall skip.
During Inspiration/Inhalation:
Diaphragm muscles contracts
External intercoastal muscle contacts
Internal intercoastal muscle relax
During Expiration/Exhalation
Diaphragm muscles relax
External intercoastal muscle relax
Internal intercoastal muscle contracts

I Agree with PIPI B,
but he forgot to mention that while inhalation the volume increases and the pressure decreases.
and for exhalation the volume decreases and the pressure increases.

The diaphram contracts and expands?

I agree with the above answer...however, they are INTERCOSTAL muscles, not intercoastal :-)
