When you inahle, air rushes into your lungs because that is the only pathway air is allowed to travel. The body is designed to be air tight and water tight where it needs to be so that no foriegn material can do damage to the rest of the body.
When you inhale, oxygen fills your lungs. Next the oxygen diffuses out of your lungs into your bloodstream. The diffusion of oxygen from the lungs causes less pressure in your lungs signaling your brain that you need to inhale.
The act of inhaling is to create low pressure in the lungs, causing the air in the atmosphere to rush in as it is moving from a higher pressure (outside in the atmosphere) to the lower pressure (created in the lungs). However the fact that air does move into the lungs means that there is no net change in pressure.
diaphragm.
There are no muscles in the lungs that help inhale or exhale, this is the job of the diaphragm.
oxygen goes into your lungs and then co2 comes out when mixed with a substance in your lungs.
When you inhale, your diaphragm contracts and moves downward, while your rib cage expands. This creates a decrease in air pressure in your lungs, causing air to rush in through your nose and mouth. Oxygen is then absorbed into the bloodstream through the alveoli in the lungs.
It travels down the trachea to your lungs.

Alligators are air breathers. They inhale and exhale through their nostrils. Their lungs absorb oxygen from the air that they inhale.
it contracts when you exhale because it is pushing the air out of your lungs.
