air contains oxygen which is a requirement for our respiration process. oxygen enters into our lungs and into the blood and carbon dioxide is excreted and then exhaled out..which is then used up plants to excrete oxygen. and thus a complete cycle!

∙ 15y ago== == ---- When you breath in, your diaphragm (a dome shaped muscular structure forming the floor of the thoracic cavity) and intercostal muscles (the muscles in the spaces between the ribs) contract. This causes the ribs to move upwards and outwards, and the diaphragm is pulled downwards, expanding the volume in the thoracic cavity. Because pressure decreases as volume increases, the pressure in the lungs becomes much less than the pressure in the atmosphere. Air moves from an areas of high pressure to areas of low pressure, so air is drawn into the lungs.

∙ 13y agoBecause air contains many nutrients such as O2, Nitrogen, and Carbon Dioxide, our body takes the air in, compresses it, and uses the nutrients to fuel our bodies. After, the used air, called methane, is sent to the intestines, where it is either farted or saved for further air use. The reason why we breathe out is to release excess nutrients from the air. Vitamins also come from air; for example, Vitamin A stands for Vitamin "Air"

lung
How air body enter and leave the body?
it goes through the trachea/windpipe into your lungs and back out
What gas do we inhale?
We normally inhale 'air' which is mostly nitrogen (approx. 78%), oxygen, (approx. 21%) a little argon and other trace gasses, the lungs extract the oxygen which the body needs and we exhale the rest with a little waste carbon dioxide which was removed from the body by the lungs.
How much nitrogen do you inhale?
In air there is 20.98% Oxygen, so that's what we inhale. We exhale 16% of this Oxygen; hence why cardiopulmonary resuscitation is possible.
How does material inadvertently enter the trachea?
If you accidentally inhale something instead of swallowing it
Where the air first enter when you inhale the air?
the trachea
How does air enter and exit our lungs?
Much like as in a concertina or a piano accordian. Body muscles increase the volume of the chest, and air rushes in to occupy the extra space. Then the body muscles reduce the volume and to avoid being pressurised the air is pushed out.
How does air enters the body?
Air enters the body when you inhale (Breathe in) air enters through the mouth and into the lungs. and then exhale (Breathe out) carbon dioxide (CO2)
Who carry oxygen to the cells of body?
no one does the air does it and we inhale it
When you inhale air enters the body through the the what?
nose or mouth
What are the 5 ways poison can enter your body?
absorb, inject, inhale, ingest, splash
Is air pressure more or less than outside the body when you inhale?
less
Which body system lets you inhale and exhale air?
The Respiratory System allows your body to inhale and exhale air. It's role is to supply the blood with oxygen. That is accomplished by breathing, that is, inhaling oxygen and exhaling carbon dioxide.
Where in one of two places air enter body?
Air can enter the body by the mouth or the nose. Air then goes down the windpipe to the lungs where it can enter the bloodstream.
What happens after animals inhale air?
The oxygen from the air they inhale is distributed to the body parts through the blood stream. The blood picks up carbon dioxide and it is exhaled into the environment.
When you inhale why does air rush into your lungs?
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.
Why does the air enter the body?
To oxygenise the body.
