Answer:

positive pressure

Explanation:

Exhalation is a passive process during which the intercostal muscles and the diaphragm relax. The ribs move downward and inward, while the diaphragm rises. This movement causes the chest to decrease in size and positive pressure to build inside the chest cavity. The positive pressure pushes air out of the lungs.
