The function of the respiratory system is to provide the body with oxygen. Oxygen enters the body through the respiratory system and is carried in blood throughout the body.
They belong to the respiratory system. This system also includes the nose and the trachea. The main goal of the respiratory system is to provide gas exchange between the blood and the environment. (AKA breathing)
