The dissolved oxygen content in fresh water is approximately 8–10 milliliters per liter compared to that of air which is 210 milliliters per liter. Water is 800 times more dense than air and 100 times more viscous. Therefore, oxygen has a diffusion rate in air 10,000 times greater than in water. The use of sac-like lungs to remove oxygen from water would therefore not be efficient enough to sustain life. Rather than using lungs, gaseous exchange takes place across the surface of highly … WebbThe main function of respiratory system is to allow gas exchange (oxygen and carbon dioxide) with different parts of the body.
