Pores of Kohn

Pores of Kohn are small communications between adjacent pulmonary alveoli and provide a collateral pathway for aeration. They are poorly formed in children and along with poorly formed canals of Lambert, are thought to be responsible for the frequency of round pneumonia in that age group.

They are typically less than 10 micrometers in diameter 1.
