Among the features of the bronchopulmonary structures of premature and immature preterm infants is a lag in the development of the arterial network from the venous one. Small and medium arteries have narrow lumen and thick muscle mass. When the lungs are unfolded, an obstacle is created for rapid blood flow in the small circle of circulation, which results in delayed unfolding of the alveoli.</p></abstract><trans-abstract xml:lang="ru"><p>Основной причиной заболеваемости у доношенных и недоношенных детей до настоящего времени остается легочная патология. Среди особенностей строения бронхолегочных структур у недоношенных и родившихся незрелыми доношенных детей следует выделить отставание в развитии артериальной сети от венозной. Мелкие и средние артерии имеют узкий просвет и толстую мышечную массу. При расправлении легких создается препятствие для быстрого прохождения крови в малом круге кровообращения, которое влечет за собой задержку расправления альвеол.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Kazan Medical archive</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>Казанский медицинский архив</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list/></back></article>
