title: [Macro- and microscopic characteristics of the glands of the human trachea and main bronchi in postnatal ontogenesis].
abstract: By means of the macro-microscopical method 68 preparations of the trachea and main bronchi, obtained from persons perished and died at the newborn age up to 90 years and having not any disease of the respiratory pathways by the time of death have been studied. The glands in the walls of these organs are adapted to the surrounding structures and have various topography in the cartilagenous and membranous parts of the trachea and main bronchi. The ductal openings in the membranous part demonstrate a regular longitudinal orientation. Despite the fact that during human life the sizes of the trachea and main bronchi increase, the amount of the glands during the postnatal ontogenesis remains nearly at the same or about the same level. With age, the density of the ductal opening arrangement per 1 cm2 of the mucosal membrane surface changes noticeably. Comparing with the newborn age, in the old age this parameter decreases nearly by 4 times.
