The oxygen enters the cells, which fuels energy production during cellular respiration. The released carbon dioxide enters the bloodstream and is transported to the lungs.
Continuous intake and exhalation should occur because the lungs always have an excess amount of air during the breathing cycle. The carbon dioxide and oxygen cycle bind plants and animals together. Animals and other living creatures require oxygen, which plants create. Carbon dioxide, a gas that plants use to manufacture their food, is produced by animals and other living organisms.
The act of breathing in oxygen and exhaling carbon dioxide is generally referred to as respiration.
Thus, we can state that oxygen enters the cells and stimulates cellular respiration, which produces energy. The released carbon dioxide travels to the lungs through circulation.
