Detailed explanation-1: -CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation.
Detailed explanation-2: -Once in the lungs, oxygen is moved into the bloodstream and carried through your body. At each cell in your body, oxygen is exchanged for a waste gas called carbon dioxide. Your bloodstream then carries this waste gas back to the lungs where it is removed from the bloodstream and then exhaled.
Detailed explanation-3: -The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
Detailed explanation-4: -The carbon dioxide diffuses out of the red blood cells, through the capillary walls, and into the alveolar spaces f exhaled.
