What causes air to be forced out of the lungs during expiration?
Air travels from areas of low pressure to areas of high pressure

Explain the mechanics of breathing (both inspiration and expiration).
Diaphragm contracts and moves downward, rib cage expands during inspiration; diaphragm relaxes and moves upward, rib cage contracts during expiration.
Diaphragm relaxes and moves upward, rib cage contracts during inspiration; diaphragm contracts and moves downward, rib cage expands during expiration.
Diaphragm and rib cage both contract during inspiration; both relax during expiration.
