Partial vacuum in the intrapleural space

Pulmonary Ventilation

Alveolar Pressure and Pleural Pressure

 The transpulmonary pressure is the difference between the intrapulmonary and the intrapleural pressure. 

 The transpulmonary pressure is the difference between the __________ and the __________ pressure. 

IP: Pulmonary Ventilation 

Boyle's Law | Respiratory System

PreLab Video Model Lung

 Boyle’s law states that volume changes lead to pressure changes, and the pressure of a gas varies inversely with its volume. 

 contraction of the diaphragm decreases the volume of the pleural cavity 

 contraction of the internal intercostal muscles decreases the thoracic cavity volume 

 the volume of the lungs decreases with inspiration 

 the gas pressure in the lungs becomes lower than the outside pressure as the diaphragm contracts 

 During inspiration, air moves into the lungs because __________.
