Question

What are two gases found in the plasma?

Answer 1

Plasma does not carry any gases. It is the fluid medium that allows red blood cells to carry oxygenated (oxygen)blood and deoxygenated (carbon dioxide) to and from the lungs.

Answer 2

Carbon dioxide is one. Do you know what the second could be? (hint: you breathe it in) :)
