POSTNATAL MORPHOFUNCTIONAL DEVELOPMENT OF THE BRONCHIAL TREE IN CHILDREN DURING THE FIRST THREE YEARS OF LIFE

Abstract

The early childhood period, spanning from age 1 to 3, represents a transformative phase in human respiratory development. This study details the postnatal ontogenetic progression of the lungs and bronchi, focusing on airway dimensions, histological maturation, and clinical implications. As the child transitions from infancy to a more active lifestyle, the bronchial tree undergoes significant structural remodeling to accommodate increased metabolic demands.
