Definitions:

Intra-Alveolar Pressure

The pressure within the alveoli of the lungs, critical in the mechanics of breathing and the exchange of gases.

Alveolar Pressure

The pressure within the alveoli, the tiny air sacs in the lungs, which is crucial for the process of breathing and gas exchange.

Pleural Pressure

Pleural pressure is the pressure within the pleural cavity, which can affect breathing dynamics by influencing the expansion and contraction of the lungs.

Thoracic Cavity

Space within the thoracic walls, bounded below by the diaphragm and above by the neck.
