MORPHOLOGICAL CHARACTERISTICS OF HUMAN TRACHEA AND BNOCHI GLANDS OF SMOKING AND NON-SMOKING ADULT MEN

Abstract

This work describes macroscopic, hystological and morphometrical study of human trachea and bronchi glands of smoking and non-smoking adult men. The study shows that number of excretory ducts of the glands in trachea, main right and distal bronchus is 3-4 times larger for smokers, rather that for non-smokers. Also, a growth of volumetric fraction of bronchial glands and mucous acini in main right and common bronchi was reliably identified for smokers versus non-smokers. These findings indicate that smoking not only increases the volumetric fraction of glads in bronchial wall, but also leads to growth of number of glands.
