How does the carbon dioxide get out of the bloodstream back into your lungs to be breathed out?

Answer 1

i don't know. is that the best answer in the world! haha YES IT'S dumb but check wikipedia thay should have here I'll check just click on this http://en.wikipedia.org/wiki/Human_lung or copy and paste it should be blue or something if not just copy and paste i didn't read the artcle yet if your Q is not there it should be updated soon.

Typically carbon dioxide doesn't come from the lungs, it goes to them and gets exhaled. However, I suppose you could inhale some carbon dioxide in which case it might diffuse into the blood and go around your body. Not really super harmful unless you inhale a lot (after all your cells naturally produce carbon dioxide through cellular respiration, which of course then travels to the aveoli and gets exhaled).

Answer 2

Taking in oxygen and giving out carbon dioxide is called breathing. Breathing is only a part of the process Respiration. In respiration, the lungs take in oxygen, which mixes with blood and is then circulated to each and every cell of the body. After this, in a cell, the oxygen is utilised for oxidation of food materials to generate energy for various metabolic processes. This process liberates carbon dioxide since it is a chemical reaction involving many steps. This carbon dioxide is then carried from each cell by the blood to reach the lungs where it is expelled out.

Answer 3

How does carbon dioxide get from your cells of your body to your lungs?

Answer 4

first we inhale carbon dioxide and then it goes through lungs and fetched by blood(artery)to heart and exhale.....
