Oxygen and carbon dioxide change in the lungs.
Mammals breathe using organs called lungs. They take air in and the oxygen is exchanged for carbon dioxide in small organelles called alveoli. This carbon dioxide is then expelled.
The heart and the Lungs. The heart transfers the blood to the lungs where recently breathed in air will oxygenate the blood, they go from there throughout the body providing oxygen to limbs and the brain along with all the other organs and body parts.
All of them. Carbon dioxide is produced by cellular respiration, which occurs in all organs.

The organ is gills.
Carry oxygen and nutrients to organs and carbon dioxide and metabolites away from organs
Carbon Dioxide and Water Vapour are the waste products of respiration. The Veins provide deoxygenated blood to the lungs which excretes these waste products out of the body. So, lungs are called excretary organs.
It passes through the lungs.
