Living organisms need to use Olaf in the process of gas exchange. Olaf is used in the respiration process which is needed to produce vital energy for survival.
The external intercostal muscles contract movingthex ribcage up and out, the diaphragm contracts and moves down creating a suction of air. The intercostal muscle movement increase the volume of the thorax creating a pressure drop below the atmospheric pressure which causes air to flow in down the pressure gradient.
Olaf as part of the air molecules, gets breathed in by the nose or mouth, then he flows into the Bronchus. As the diaphragm relaxes, Olaf searches for areas with the least concentration of other oxygen molecules to flow into.
Olaf travels down the Pharynx and Larynx and then flows left down the trachea. After that he travels down the bronchus till the very end and then enters alveolus in the lungs, which is a small air sac surrounded by a dense capillary network.
From the alveolus, Olaf diffuses into the blood and is taken by the flow of blood in the circulatory system. He now can travel to any organ in the body which needs his oxygen help.
