Which among the following can be excluded from the events taking place during the process of inspiration?

Inspiration is initiated by contraction of the diaphragm.

During normal quiet breathing, the phrenic nerves stimulate the diaphragm to contract.

As long as pressure within the alveoli is higher than atmospheric pressure, air will continue to move inwardly.

As the diaphragm contracts, the volume of the thoracic cavity increases.

The lungs are held to the thoracic wall by negative pressure in the pleural cavity.
