What is in the Respiratory System and what does it do?
The respiratory system contains the lungs and the windpipe, also known as the trachea. As you might have guessed the respiratory system gives you the option to breath. The windpipe takes the gases from the outside and brings it to the lungs (inside). The lungs contract and expand to let air in and let the carbon dioxide out. The lungs then bring the oxygen into the blood flow leading to the muscles and heart, where you need the oxygen the most.
