The main function of the respiratory system is to take in oxygen and expel carbon dioxide. This is made possible through various organs and the lungs being the main ones as they exchange the gasses as we breathe. Do you have a proper understanding of how a healthy respiratory system runs? Take this test and demonstrate your knowledge of how it operates.
