Forms a passageway through which air passes, they connect the bronchus and alveoli
Define alveoli
Found in the lungs and there are thousands of these in the lungs and they increase the surface area in the lungs
Define pleural fluid
A fluid secreted by the pleural membrane, it reduces friction between the lungs and the ribcage during ventilation
