Wow, so there are a few answers to this:

-The apnuestic center in the brain controls repirations.

-The diaphragm is the muscle that helps move the lungs up and down.

-The sudden drop in negative pressure in our chest cavity that signals our lungs to take a breath in once we have enhaled the last breath out.
