WitrynaAn opening in the thoracic cage, combined with the negative intrapleural pressure, allows air to enter the pleural space. The lungs will collapse because of their elastic recoil, and the chest wall will expand outward. Contraction of the diaphragm then causes air to enter the intrapleural space rather than to inflate the lungs. WitrynaExplanation with a diagram: Inhalation: During inspiration, intrapulmonary pressure is negative, allowing outside air to enter, and during expiration, intrapulmonary pressure becomes positive due to a decrease in pulmonary volume. This forces the air out into the lungs. Exhalation: Even when exhaling, the pressure inside the pleural cavity around …
