The percentage of O2 and CO2 differ greatly in inhalation and exhalation. CO2 levels tend to be higher in exhaled air as it is a metabolic waste product. O2 levels tend to be lower in exhaled air as it is absorbed from the air and used by the metabolism.

During inhalation, air rich in oxygen is taken in through the nose or mouth and travels to the lungs. During exhalation, air rich in carbon dioxide is expelled from the lungs through the nose or mouth. This process is essential for the exchange of gases in our body to maintain proper levels of oxygen and carbon dioxide.

Exhaled air - is the carbon dioxide that we breath out as a product of cellular respiration. Inhaled air is the oxygen we take in that is required for the process of cellular respiration. Along with the oxygen we take in are other elements such as Nitrogen, which we don't use and it doesn't harm us. It's just a by product of breathing.
