Answer:
In the Heart.
Explanation:
The deoxygenated blood, from all parts of the body is collected by the veins and is carried to the heart, where the deoxygenated blood is converted into oxygenated blood by adding oxygen into it. The alveoli are the sites of exchange of carbon dioxide and oxygen.
From the alveoli, the oxygen diffuses into the blood and the carbon dioxide is diffused into the air which is then exhaled out by us.
