Oxygen is taken by the lungs for the body to use, while carbon dioxide is a waste product expelled by the body. This gas exchange process is vital for cellular respiration and cell function.
Oxygen is the gas that the lungs take from the air for the body to use. It is essential for cellular respiration to produce energy in the form of ATP. When oxygen is inhaled, it enters the bloodstream and is carried to cells where it is used for various metabolic processes.
Carbon dioxide, on the other hand, is a waste product produced by cells during aerobic cellular respiration. It is transported back to the lungs through the bloodstream and expelled from the body during exhalation.
The exchange of gases between the body and the atmosphere, with oxygen entering the body and carbon dioxide being expelled, is crucial for the survival and proper functioning of cells and tissues.
