The study was conducted on the serial histological sections by using morphometry and volumetric graphic reconstruction of the acini. In a typical acinus, three generations of the respiratory bronchioles, four generations of the alveolar ducts, and one generation of the alveolar sacs (AS) were found. All the intraacinar components branched in the form of dichotomy, most commonly, irregular. It was shown that the acini were regularly asymmetrical, 32% of branches of the alveolar ducts of the second order had no continuation and ended with AS. In the same way, two thirds of the third order alveolar ducts also continued into AS, i. e. about 40% of branches are rudimentary. Intra-acinar path from the first alveoli in the respiratory bronchioles to the terminal alveoli is equal to 7.2±1.0 mm. The peculiar feature of the acinus of the Siberian residents is an increased transitional zone and a distal shift of respiratory zone by one generation of branches in the direction from the conducting airways, which reduces its cooling during breathing cold air in winter.</p></abstract><trans-abstract xml:lang="ru"><p>Архитектоника и параметры ацинуса легких изучены у 6 мужчин в возрасте 19-27 лет, постоянно проживавших в г. Новосибирске. Исследование проводили на серийных гистологических срезах с использованием морфометрии и объемной графической реконструкции ацинусов. Установлено, что в типичном ацинусе у них определяются 3 порядка ветвления респираторных бронхиол, 4 - альвеолярных ходов и 1 - альвеолярных мешочков (АМ). Все внутриацинарные ходы ветвятся в форме дихотомии, чаще неправильной. Показано, что ацинусы закономерно асимметричны, 32% ветвей альвеолярных ходов второго порядка не имеют продолжения и заканчиваются АМ, от 2/3 альвеолярных ходов третьего порядка также отходят АМ, т.е. около 40% ветвей рудиментированы. Внутриацинарная дорожка от первых альвеол в респираторной бронхиоле до терминальных альвеол составляет 7,2±1,0 мм. Особенностью ацинуса жителей Западной Сибири является увеличение транзиторной зоны и смещение респираторной зоны на один порядок ветвления в дистальном направлении от воздухоносных путей, что уменьшает её охлаждение при дыхании холодным воздухом в зимнее время года.</p></trans-abstract><kwd-group xml:lang="en"><kwd>human pulmonary acinus</kwd><kwd>acinar microstructures</kwd><kwd>transitional zone</kwd><kwd>respiratory zone</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>ацинус легких человека</kwd><kwd>микроструктуры ацинуса</kwd><kwd>транзиторная и респираторная зоны</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Вейбель Э.
