From: Morphometric Analysis of Mouse Airways After Chronic Allergen Challenge

A, Depiction of the lobes of a mouse lung after inflation and fixation with formalin. The left lobe and right inferior lobe were bisected. Sections for staining were obtained from the exposed surfaces of the right lobe segments, and from regions corresponding to the extreme inferior and superior borders of the middle third of the left lobe (all sections indicated by dashed lines). B, Typical first generation airway from the left lobe with associated artery and vein. Airway images captured for analysis indicated in boxed regions.
