The respiratory system is made up of several organs and structures that work together for gas exchange. The right and left lungs reside in the thoracic cavity and are divided into lobes. During breathing, the diaphragm and intercostal muscles work to decrease pressure in the chest cavity, causing air to flow through the trachea and into the lungs. In the lungs, gas exchange occurs in alveoli via a network of bronchioles and pulmonary blood vessels.
