WebAtmospheric pressure is the pressure of the air outside the body. Intraalveolar pressure is the pressure inside the alveoli of the lungs. Intrapleural pressure is the pressure within the pleural cavity. These three pressures are responsible for pulmonary ventilation. Inspiration. Inspiration (inhalation) is the process of taking air into the lungs. WebApr 10, 2024 · Kenny and Ponichtera (2024) state that, at the base level, the thoracic cavity is in static equilibrium, and its intrapleural pressure is approximately at -5 cmH2O. When inspiration occurs, inspiratory muscles contract, which increases intrathoracic volume.
