Abstract: The aim of the study was to reveal changes in the morphofunctional state of the respiratory part of the lungs in postnatal ontogenesis. The material for the study was the lungs of 23 rabbits aged from 1 to 180 days after birth. The respiratory part undergoes the most substantial morphofunctional changes in the course of early postnatal development. The pulmonary acini in one- and ten-day-old animals have a primitive structure. From the fifteenth day their expansion takes place, with the formation of alveolar ducts and alveoli; in one-month-old rabbits the structure of the acinus becomes almost the same as in adults. The argyrophilic and especially the elastic fibres gradually thicken. Alkaline phosphatase activity is revealed as moderate at most periods of the study, rising on days 7, 15 and 30 after birth.
