I don't understand how oxygen and carbon dioxide move through the body.
Can someone explain?
Can someone explain?
It may be a bit more helpful if you ask some more specific questions. How in depth of an answer do you want? =)
Okay
I understand why oxygen diffuses from the lungs to the capillaries and carbon dioxide diffuses into the alveoli. The oxygen moves from a high pressure gradient to a lower pressure gradient. Once this occurs, where does the oxygen and carbon dioxide diffuse to.
