Inhalation vs. Exhalation: Know the Difference
By Shumaila Saeed || Published on January 31, 2024
Inhalation is the process of taking air into the lungs, while exhalation is releasing air out of the lungs.
Key Differences
Inhalation involves drawing air into the lungs, primarily to absorb oxygen. Exhalation, in contrast, is the expulsion of air from the lungs, primarily to expel carbon dioxide.

During inhalation, the diaphragm contracts, creating a vacuum that pulls air into the lungs. Exhalation occurs when the diaphragm relaxes, and the lungs contract, pushing air out.

Inhalation is the first step in the respiratory process, supplying the body with oxygen. Exhalation is the final step, removing carbon dioxide, a waste product of metabolism.
