In the alveoli, fresh oxygen and carbon dioxide swap places. Then carbon dioxide is released out to the environment when you breathe out.

A Hit to the Lungs

Using e-cigarettes/vapes could lead to bronchitis, which is swelling and irritation of the major airways in the lungs. This makes it harder for air to get in and out of the lungs.

Using e-cigarettes/vapes can lead to emphysema, which is the destruction of air sacs in the lungs. Emphysema is common in long-term cigarette smokers.
