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 human action causes the lungs to become filled with air?
breathing is the human action that causes the lungs to be filled with air.
What occurs when the air pressure in the lungs is higher than in the atmosphere?
When the air pressure in the lungs is higher than in the atmosphere, air will flow out of the lungs to equalize the pressure. This is called exhalation. It allows the body to get rid of carbon dioxide and regulate oxygen levels.
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.

When the lungs expand does it fills with air from the atmosphere?
Yes
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 atmosheric pressure and what causes it?
Atmospheric pressure is the force exerted by the weight of air in the Earth's atmosphere. It is caused by the gravitational pull of the Earth on the air molecules and decreases with altitude.
What is the percentage of air you breath from the atmosphere?
the atmosphere IS air... which the gravitational pull of the earth keeps here
Under what condition does air flow goes in to the lungs?
when pressure inside the lungs is lower then outer atmosphere
What causes air to move in and out of your lungs?
the expansion and relaxation of your diaphram.
Where do deer get air?
The deer most likely use their mouth or nose. They then expand their chest or lungs to withdraw the air from the atmosphere. The air then travels though the mouth or nose into the lungs.
