Relevance: The purpose of choosing this topic is related to the need to study the cellular structures of the respiratory epithelium. The mucous membrane of the respiratory tract consists of a complex system of cells that perform protective functions. The sources contain studies on the microscopic structure of the epithelial lining of the trachea and age-related features of the transport function, but there is little information about the epithelial layer of the bronchi. The purpose of the study is to study the morphological structure of the bronchial wall of deceased patients without respiratory system diseases. Materials and methods. In 2020-2024, a complex histological and histochemical examination of bronchial wall fragments and lung tissue sections of 26 deceased individuals aged 45 to 70 years without respiratory system diseases was conducted at the Department of Pathological Anatomy of the Multidisciplinary Clinic of Samarkand State Medical University. Research results: The muscular layer of the mucous membrane of the wall of the large-caliber bronchi consists of 3-5 rows of smooth muscle cells, which have a weak basophilic nucleus and eosinophilic cytoplasm. The submucosal layer of the bronchi consists of bundles of connective tissue fibers and hyaline cartilage, there are hyaline cartilage plates that are interconnected by thin connective tissue fibers, which in turn form a fibrous cartilage layer. Conclusion. Data obtained as a result of histological and histochemical examination of fragments of bronchial walls and lung tissue taken as samples from deceased adult patients without respiratory system diseases.
