carbon dioxide
blood takes oxygen and gives carbon dioxide to the lungs
oxigen is the gas that enters the blood through the lungs
The flow of blood in the body is facilitated by the pumping action of the heart, which carries oxygenated blood from the lungs to the rest of the body and returns deoxygenated blood to the lungs for reoxygenation. Gas exchange occurs primarily in the alveoli of the lungs, where oxygen from the air diffuses into the bloodstream and carbon dioxide is released from the blood into the air to be exhaled.

Carbon Dioxide
gas exchange takes place in the lungs, and at the cellular level. In the lungs, carbon dioxide and other "waste" gasses are released from the blood to be exhaled, and oxygen is absorbed into the blood. At the cellular level, oxygen is released from the blood into a cell, and carbon dioxide and other "waste" gasses are passed into the blood.
Oxygen is the gas that enters the blood during inspiration. It is taken into the lungs from the outside air and then diffuses into the blood vessels in the lungs.
Gas exchange also occurs in the alveoli of the lungs, where oxygen from the air is taken up by red blood cells and carbon dioxide is released. Additionally, gas exchange occurs in the gills of fish, where oxygen from water is absorbed by blood vessels and carbon dioxide is released.
