interlobular septa

The interlobular septa (singular: interlobular septum) are located between the secondary pulmonary lobules and are continuous with both the subpleural interstitium (peripheral connective tissue) and the peribronchovascular interstitium (axial connective tissue) as well as the more delicate intralobular septa.

These septa are composed of connective tissues within which run the pulmonary veins and lymphatics which drain towards the pleura. A second set of lymphatics runs along with the arteries and drains centrally.

The interlobular septa are incomplete allowing for communication between adjacent secondary pulmonary lobules (canals of Lambert and pores of Kohn).
