Canine lung anatomy requires further study for functional bronchopulmonary segmentation (BS). Understanding canine BS, involving bronchi, arteries, and veins, is crucial for advancing veterinary surgical techniques like segmentectomy.
Area of Science:
- Veterinary Anatomy
- Pulmonary Medicine
Background:
- Bronchopulmonary segmentation (BS) is crucial in human medicine but poorly understood in veterinary practice.
- Current veterinary nomenclature for canine lungs lacks functional categorization based on bronchial segments.
Purpose of the Study:
- To review and analyze the anatomical basis for bronchopulmonary segmentation in canine lungs.
- To identify gaps in knowledge and suggest future research directions for canine lung anatomy.
Main Methods:
- Comparative analysis of existing veterinary literature on canine lung anatomy.
- Review of anatomical structures essential for bronchopulmonary segmentation (bronchi, arteries, veins, septa).
Main Results:
- Canine lungs possess the fundamental anatomical components for bronchopulmonary segmentation.
- Existing literature lacks detailed descriptions, particularly regarding venous drainage and variations.
Conclusions:
- Further research is needed to detail canine bronchopulmonary segmentation, including venous drainage and anatomical variations.
- Establishing canine BS could facilitate the development of segmentectomy in veterinary surgery.

The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
