intercostal muscles in your ribs pull the chest cavity apart which enlarges the lungs, your diaphram also flattens out which makes the thoracic cavity larger as well. The lungs become larger while the concentration of air inside them stays the same...so what happens? Naturally, the air pressure in the lungs decreases which causes air from the environment to rush into the lungs to balance the air pressure.
Oh and dude, dont trust any answers you get on this site, there are a lot of people posing to be professionals just to act cool or whatever they get out of it. Just get a tutor or start a study group in your class.

Obesity,ectomorphic built,increased blood pressure,full abdomen ,fluid in abdomen,pregnancy,smoking,airway obstruction in the form of allergy, infections and growths decrease it.
