Carbon dioxide leaves the blood and goes into the alveoli where it can then be breathed out of the body. It is also at this point that oxygen passes into the blood to be carried to where it is required for respiration - carbon dioxide being a by-product of respiration.
Gases are exchanged in the aveoli where oxygen goes in the blood stream while carbon dioxide goes in the aveoli.

Squamous pneumocytes are epithelial cells that line the inside of the aveoli, the tiny sacs in the lungs that allow for gas exchange between air and the blood.
