What vertebrae are the coastal processes located?

What property of the thoracic cage causes expiration?
The elasticity of the thoracic cage, including the ribs and intercostal muscles, causes expiration. During expiration, these structures recoil back to their resting position, pushing air out of the lungs.
What happens to the volume of the thoracic cavity during the respiratory cycle?
During inspiration, the volume of the thoracic cavity increases as the diaphragm contracts and the rib cage expands. This allows air to be drawn into the lungs. During expiration, the volume of the thoracic cavity decreases as the diaphragm relaxes and the rib cage recoils, causing air to be expelled from the lungs.
