what gas do you carry out of your lungs?

Answer 1

CO2 (carbon dioxide)

Answer 2

Not all of the oxygen that you breath in is absorbed into the capillaries surrounding the alveoli of the lungs, which means there is some present in air that you breathe out. Carbon dioxide is also present in you exhalation since it is a waste product of respiration and needs to be removed. There are trace gasses such as nitrogen and hydrogen as well but this is mainly because they are present when you inhale and are not transferred into the blood when in your lungs. There is also a small amount of water vapour exhaled, however this is an unwanted loss and mechanisms exist in your lungs that limit the amount lost.

Answer 3

Carbon dioxide is a waste product of your cells. It is very dangerous if it builds up in your body. Your blood carries the carbon dioxide from your cells to your lungs, to let you breathe out all the bad gas!

Answer 4

The same gasses you inhaled, nitrogen, oxygen, carbon dioxide, etc., except the oxygen content drops from 21% to about 19% with a corresponding 3% increase in carbon dioxide concentration.

Hemoglobin in your blood exchanges carbon dioxide for oxygen when moving through your lungs. Although you don't strip all the oxygen out of the air in your lungs.

I'll bet the answer is in your book somewhere.

Answer 5

You inspire 21% oxygen (O2) and expire about 16-17% xygen, the short fall between these two being made up by carbon dioxide (CO2). Most of the rest is nitrogen with a few other trace gases

Answer 6

CO2, also known as carbon dioxide

Answer 7

carbon dioxide and a bit of something else, but mainly CO2

Answer 8

Nitrogen, carbon dioxide, oxygen and possibly other trace gases, depending what environment you are in.

Answer 9

Co2

Answer 10

Carbondioxide, CO2 and water vapor
