The pulmonary vessels and their endothelium plays the role of a physiological barrier for numerous biologically active substances, then the epithelium and connective tissue basis of the airways perform a barrier-protective function in relation to various environmental factors [1]. The bronchial secret produced by the mucous membrane is the result of the complex integration of the transudation of the plasma components of the blood, the secretory activity of the bronchial epithelium, glands, the cells of the connective tissue and blood cells (neutrophils, fat cells, eosinophils, macrophages, etc.). From the presented few literature presented, it becomes obvious that the structure of the lung function is closely integrated with the lymphatic system. Located in the immediate vicinity of both peribronchial and alveolar blood capillaries, the flow of lymph goes along the bronchial tree and along the subpleural tissue, in its most lungs and the lymph nodes located here, as well as tangential along the plane of the pleura [2.3] .

Based on the foregoing, the purpose of this work is to establish in posttal ontogenesis the laws of the formation and involution of bronchial vascular and lymphatic systems in a person, epithelial connective tissue relationships in the air and respiratory parts of the lung (1.4).
