These septa are located at the periphery of the lungs, forming the visible polygonal boundaries that demarcate individual secondary pulmonary lobules on the lung surface.
What is the function of the pulmonary interlobular septum?
The septa provide structural support and contain pulmonary arteries, veins, and lymphatic vessels that distribute throughout the lung parenchyma.
What is the pulmonary interlobular septum connected to?
The septa are continuous with the visceral pleura, connecting adjacent lobules and containing branches of the pulmonary and bronchial circulations.
Why is the pulmonary interlobular septum clinically important?
Thickening of interlobular septa is a classic radiological sign of pulmonary edema, lymphangitis carcinomatosa, or pneumoconiosis, aiding in diagnosis of diffuse lung disease.
