We have air in the body. Our lungs.
Your lungs
I think you mean the diaphragm, and that's part of the respiratory system. It's a muscle below the lungs, and when it tightens, it increases the volume of the cavity the lungs are in, so the lungs increase in volume as well, and air rushes into the lungs.
This is called the Respiratory System. It allows the body to breathe and receive air.

lungs
The frogs' chin goes down, pulling air into the vocal sac. Then, it's nostrils shut and the chin goes up, forcing the air into the lungs. When they oxygen is taken, the chin will go down, pulling the air our of the lungs. Then the nostrils open up, and the chin will go up, pushing the air our of the chin. Then repeats.
The respiratory system exchanges gases between air and blood. This process occurs in the lungs, where oxygen is taken in from the air and carbon dioxide is released from the blood into the air.
