When you breathe in, air enters the body (via mouth or nose) and travels down a tube called the windpipe (aka trachea) and into the lungs. When you exhale, carbon dioxide gas is released. Heres something fun for you to try, take a deep breath (inhale with your nose) and try and imagine oxygen going into the lungs. Hope this helped:)
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.
Yes
when pressure inside the lungs is lower then outer atmosphere
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.
Atmosphere
The fox gets its air from the atmosphere as do all animals.
This statement is not accurate. There are typically billions of atoms in a single breath of air and trillions of breaths in the Earth's atmosphere, making the comparison between the two vastly different. The number of atoms in your lungs is very small compared to the total number of breaths in the atmosphere.
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.
The lungs are the only internal organs that are in direct contact with the atmosphere, as they exchange gases with the air to facilitate respiration.
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.
The main function of a pig's trachea is to breathe. It is part of system of passages that allow air into the lungs.
your lungs silly through your mouth and nose. unless you are talking about gas and that is a chemical reaction inside your body and that's a different kind of air. or an accidental needle air bubble can be put in the vien but that kills you
