Abstract

We studied the dynamics of morphometric parameters of lung in 1-20 day-old piglets. Morphometric parameters of lung asynchronously increase with age. We found that the lungs of newborn pigs characterized by significant incomplete struc-tures and the presence of areas of atelectasis in all fractions of the body. Bronchial structure depends on the degree of their differentiation. Alveolus has varying clear-ance while the terminal bronchioles possess nearly constant diameter. Absolute lung weight increases asynchronously with age of the animals, and the relative lung

weight tends to fall in the 15 - and 20 - day old piglets, due to the intense growth of their body weight.
