What would you like to do?
Do you inhale or exhale when gases inside the lungs are pushed out through air passages?
Was this answer useful?
Thanks for the feedback!
Inhaled air Nitrogen: 78% Oxygen: 21% Carbon Dioxide: 0.04% Water Vapour: 0.96% Exhaled Air Nitrogen: 78% Oxygen: 17% Carbon Dioxide: 4% Water Vapour: 3%
I believe that the pressure from the diaphragm causes our lungs inflate, thus we inhale and when the diaphragm deflates, it makes us exhale. -------------------------------…-------------------------------------- As your diaphragm or intercoastal muscles contract the size of the lungs increases. This creates a pressure difference between your lungs and the surrounding atmosphere. By increasing the size of the lungs you create a low pressure environment in the lungs by expanding the same amount of gas to a larger area. this pressure difference doesn't have to be much 1mmhg is more then enough, the main thing is just that you need a difference in preasure. Air flows from high preasure to low preasure, so by decreasing the preasure in the lungs air flows into the lungs. as you breath out you make the lungs smaller by relaxing the muscles and diaphragm, making the volume in the lungs decrease, thus increasing the preasure and moving the air from inside the lungs out to the surrounding atmosphere.
If you don't know, then look somewhere else because answers.com knows NOTHING. But if you really need to know the answer, it's water and carbon dioxide.
When this happens, your lungs and the rib cage (with muscles between each rib) expand when inhaling, and return to their previous size.
am doing that in my science class right now. am tryna figure out the same thag. help me! :)))
we inhale rufly 80% nitrogen 15% oxyegen and about 0.03% carbon dioxide
You should especially inhale through the nose when it is cold. Cold air damages the fragile linings of the respiratory tract. Blood vessels in the nasal cavity warm inhaled ai…r to reduce the damage caused. If you breathe through the mouth, air is not warmed, leaving you at risk of catching chest infections such as pneumonia. If possible, breathe out through the nose as well, but it doesn't matter so much if you exhale through the mouth, because the exhaled air has already been warmed in your body.
Oxygen and Carbon Dioxide. (:
Oxygen and nitrogen. We inhale ≈ 21% oxygen the rest is nitrogen We exhale ≈ 16% oxygen, 5% carbon dioxide and the rest is nitrogen
Because the body has used the oxygen in the air to oxidize the nutrients you eat, this process combines the oxygen that you inhaled with carbon which makes up part of the nutr…ients you eat to form a poisonous gas "carbon-dioxide" which is then transported back to the lungs and exhaled along with moisture.
When you breathe in, your diaphragm will contract, causing your lungs to expand and suck in air. When you breathe out, your diaphragm will relax, causing your lungs to shrink …and force out air.
You exhale because you're body is getting rid of the gases so the oxygen can come into your lungs.
When you inhale, you breathe in a mixture of Chloroform and Chlorine (in the scientific world, we call them the "2 Chl's") They are essential for life as we know it. Oxygen is… not essential for life. That was a rumor put out there by air freshener companies that wanted to boost profits.
