Then most people think of the respiratory system, they naturally focus on the lungs and breathing. Indeed, breathing is a necessary function of a healthy body. Without the lungs taking in air, the cells of the body could not operate properly. However, the lungs are only one part of the respiratory system. The respiratory system also includes the nose, mouth, pharynx, larynx (voice box), trachea (windpipe), bronchi, alveoli, and diaphragm.
