diaphram contracts and flattens out, increasing the length of the thoracic cavity, intercostal muscles contract, elevating the ribs and increasing the diameter of the thoracic cavity.
diaphram and intercostal muscles relax; decrease in size of the thoracic cavity increases pressure, and air moves out of the lungs.
