Abstract:
The objective of this study is to describe the airway model with bronchial ramification in porcine lung. The lungs of pig were right and left and not uniform in size which was located in the greater part of thoracic cavity. The right and left lungs were divided into lobes by cardiac notch and interlobar fissures. The apical lobe of right lung was larger than the left, undivided and supplied by separate apical bronchus. The right primary bronchus given off five ventro-lateral (RVL₁ to RVL₅), four ventro-medial (RVM₁ to RVM₄), three dorso-medial (RDM₁ to RDM₃) and two dorsal (RD₁ to RD₂) secondary branches and continued as terminal branch for right lung. The left primary bronchi given off secondary bronchi such as five ventro-lateral (LVL1 to LVL5), three dorsal (LD₁ to LD₃), two ventro-medial (VM₁ to VM₂) and continued as terminal branch for distribution to different lobes of left lung.
