Having knowledge on models of the bronchial tree branching, is of a special interest for clinical and surgical pulmology, because the hemilobectomy, segmentectomy and subsegmentectomy are always determined by intralobar, intrasegmental and intrasubsegmental bronchial ramification. Investigations were performed on 100 lungs of children and adults of both sexes, one day to 85 years old, randomly chosen. There are two main types of branching of the left upper lobe bronchus: the bifurcation pattern as dominant model in 74% and the trifurcation model found in 26%. Out of 100 lungs studied, 21 lungs had the ventilatory variations of the bronchopulmonary segments. The classification and categorization of the ventilatory of bronchopulmonary segments of the left upper lobe of lung were made. This classification contains 5 categories and 8 subcategories.
