WebYour belly and chest should both expand when you inhale. When you exhale, your chest relaxes, and your navel pulls back in toward your spine. This type of deep breathing tells your body to relax ... WebAn 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.

WebIntra-alveolar pressure (intrapulmonary pressure) is the pressure of the air within the alveoli, which changes during the different phases of breathing (Figure 2.14). Because the alveoli are connected to the atmosphere via the tubing of the airways (similar to the two- and one-liter containers in the example above), the intrapulmonary pressure of the alveoli … WebThe mechanism of breathing obeys Boyle’s law which states that that in a closed space, pressure and volume is inversely related as the volume decreases, pressure increases and vice versa. The thoracic cavity always has a slight, negative pressure which aids in keeping the airways of the lungs open.
