Answer: The respiratory system moves air in and out of the body. When you breath in oxygen this creates oxygenated blood. The blood moves through the aorta which then distributes the oxygenated blood to rest of the body. The co2 then leaves the lungs when you exhale. Hope this helped. :)

Answer: The respiratory and circulatory system work together to make gas exchange possible because on the air sacs inside the lungs there are lots of cavalries which allow the oxygen poor and oxygen rich blood to flow through. There has exchange occurs. The oxygen gets filtered into the oxygen poor blood and the carbon dioxide gets released back into the lungs, which we then exhale.
