Explain mechanism of inhalation and exhalation ?

During inhalation, the diaphragm is contracted which increases the volume of the lung cavity. During exhalation, the diaphragm is relaxed which decreases the volume of the lung cavity. As the intercostal muscles relax, air passively leaves the lungs. This type of breathing is also known as shallow breathing.
