pores of Kohn

(pŏrz)
[Hans Kohn, Ger. pathologist, 1866–1972]
A passageway for gas from one alveolus of the lung to an adjacent one. These may be of assistance in preventing atelectasis.

Three in particular: Pores of Kohn, Martin Channels and Lambert Channels are terms that make up collateral ventilation (CV) and are an example of this.
Pores of Kohn are filled in normal lungs: low-temperature scanning electron microscopy.
Pores of Kohn are apertures in the alveolar septum, which are circular or oval in shape and allow communications among adjacent alveoli [2].
However, the effects of pores of Kohn on acinar deposition remain unclear and underinvestigated.
Structurally, there are septal walls and pores of Kohn between neighboring alveoli, which are expected to strongly affect airflow and particle deposition, but whose influences have rarely been studied.
To study particle deposition in these regions, we started with a simplified four-sac alveolar model, with septal walls and pores of Kohn between adjacent sacs.
There were openings (i.e., pores of Kohn) connecting any two neighboring alveoli, and thus totally five pores existed in this model geometry (Figure 1(a), middle panel).
Nodular patterns of edema have also been described with underlying emphysema, attributed to the impairment of collateral ventilation through the pores of Kohn and channels of Lambert.(6)
I would have called my band "The Pores of Kohn" or maybe something funky like "The Non-Re-breathers" or something very stark ala Sting, like maybe "PHLEGM".
The pattern of atelectasis typically depends on the extent of collateral ventilation, which is provided by the pores of Kohn and the canals of Lambert.
The alveoli are laced with the Pores of Kohn, intercommunications between the alveoli that allow for collateral ventilation.
Many authors posit that these passageways, along with intersegmental respiratory bronchiolar pathways that exist primarily in the lower lobes, may be as important as the Pores of Kohn regarding the success of lung re-inflation therapy to aid in the treatment and resolution of atelectasis and pneumonia.
