what gas is removed from inhaled air?

Why do you inhale air? What in the air do you need to continue to live?

oxygen

The gas that is removed from inhaled air during the process of respiration is carbon dioxide (CO2). When we breathe in, we take in oxygen (O2) from the surrounding air into our lungs. Oxygen is necessary for the body's cells to function properly. During cellular respiration, the cells use oxygen to produce energy.

On the other hand, as the cells perform their metabolic activities, they produce carbon dioxide as a waste product. This carbon dioxide, high in concentration within the cells, is then transported back to the lungs through the bloodstream. When we exhale, the carbon dioxide is expelled from the body as waste.

The removal of carbon dioxide from the body is essential to maintain proper pH balance and prevent a buildup of this waste gas.
