The main organs of the respiratory system are the nose, pharynx, trachea, bronchi, and lungs.he respiratory system â¦ does this through  breathing. When we breathe, we inhale oxygen and exhale carbon  dioxide. This exchange of gases is the respiratory system's means  of getting oxygen to the blood. To ensure that the body receives  enough oxygen and to expel waste, carbon dioxide.
Air is not only filtered, but is also moistened and warmed before entering the lungs. The organs of the respiratory system are designed to perform two basic functions: (1) they serve as an air distributor, and (2) they serve as a gas exchanger for the body. This system also effectively (1) filters, (2) warms, and (3) humidifies the air we breathe.
