Pores of Kohn
The pores of Kohn (also known as interalveolar connections or alveolar pores) are discrete holes in
Etymology
The pores of Kohn take their name from the German physician and pathologist Hans Nathan Kohn (1866–1935) who first described them in 1893.[3][4]
Development
They are absent in human newborns. They develop at 3–4 years of age along with
Function
The pores allow the passage of other materials such as fluid and bacteria, which is an important mechanism of spread of infection in lobar pneumonia and spread of fibrin in the grey hepatisation phase of recovery from the same. They also equalize the pressure in adjacent alveoli and, combined with increased distribution of surfactant, thus play an important role in prevention of collapse of the lung.[6]
Unlike adults, in children these inter-alveolar connections are poorly developed which aids in limiting the spread of infection. This is thought to contribute to
