WebAs you breathe in, oxygen from the atmosphere enters the lungs and moves into the circulation through the capillary walls that surround the alveoli of the lung. When you exhale, both carbon dioxide and ethanol in the breath are removed from the blood (of course, not all of it!). Let’s look at this more closely. The main reason for exhalation is to rid the body of carbon dioxide, which is the waste product of gas exchange in humans. Air is brought into the body through inhalation. During this process air is taken in by the lungs. Diffusion in the alveoli allows for the exchange of O2 into the pulmonary capillaries and the removal of CO2 and other gases from the pulmonary capillaries to be exhaled. In order for the lungs to expel air the diaphragm relaxes, which pushes up on the lungs. The air …
