By expanding them, you create a vacuum inside them; given a portal (your mouth, nose), the vacuum will pull the ambient air in, just as a vacuum cleaner pulls things inside by creating a vacuum.

How does the diaphragm pull air into and out of the lungs?
When the diaphragm expands, causes the lungs to become smaller forcing all the air in the lungs to be pushed out since there is more pressure. When the diaphragm contracts, it makes more room for the lungs to expand, forcing air in the lungs since there is more space.
What occurs when the air pressure in the lungs is higher than in the atmosphere?
The air comes out of the lungs.
What human action causes the lungs to become filled with air?
breathing is the human action that causes the lungs to be filled with air.
When the lungs expand does it fills with air from the atmosphere?
Yes
What causes a breath to be taken?
The lungs will expand and the diaphragm will pull down to let air come in. The ribcage will also expand out for more room.

Why does air rush into the lungs during the process of breathing?
Air enters the lungs because the pressure in the atmosphere is greater than the pressure in the lungs. Lung pressure is lowered by increasing the volume of the lungs. This is achieved by lowering the diaphragm and raising the rib cage.
What is the percentage of air you breath from the atmosphere?
the atmosphere IS air... which the gravitational pull of the earth keeps here
What causes atmospheric air to be rapidly heated?
In the atmosphere, warm surfaces can heat the air above them. High pressure in the atmosphere is what causes the air to rapidly heat.
Why doesnt a balloon float with your air?
The air from your lungs has the same density as the air in our atmosphere. As a result a balloon inflated by a human using their lungs is unable to float.
Under what condition does air flow goes in to the lungs?
when pressure inside the lungs is lower then outer atmosphere
There are about as many atoms of air in your lungs at any moment as there are breaths of air in the atmosphere of?
the whole world
