В норме в ответ на увеличение давления в желудке его тонус увеличивается; 2) При гакстроэзофагеальной рефлюксной болезни (ГЭРБ) на каком-то этапе, в зависимости от степени недостаточности функции НПС и величины желудочного давления, кардиальный отдел желудка не выдерживает нагрузки и раскрывается, что проявляется увеличением угла Гиса, появлением угловой деформации желудка в виде «клюва» или укорочением функционирующей части НПС, а также уменьшением газового пузыря желудка; 3) Пилорический сфинктер (ПС) является истинным сфинктером. Эвакуация из желудка происходит в результате раскрытия ПС под воздействием порогового давления в предсфинктерной зоне антрального отдела желудка; 4) В вертикальном положении эвакуация начинается, когда высота уровня химуса над ПС создает гидростатическое давление, превышающее пороговое давление; 5) Когда гидростатическое давление снижается ниже порогового уровня и всегда в горизонтальном положении пороговое давление создается в результате смыкания глубокой перистальтической волны и образования в антральном отделе замкнутой полости;. 6) Порционность эвакуации обеспечивается двумя путями; а) объем антральном полости соответствует объему луковицы ДПК; б) в вертикальном положении после заполнении луковицы сокращается постбульбарный сфинктер, в результате чего давление в луковице поднимается, что приводит к рефлекторному сокращении ПС и прекращению эвакуации.</p></abstract><trans-abstract xml:lang="en"><p>The publication is based on a retrospective analysis of 344 radiological studies of the upper digestive tract and analysis of the literature. We propose the hypothesis of the gastric motility, based on the following points: 1) The gastric cardia is the intra-abdominal portion of the lower esophageal sphincter (LES). Its tone increases in response to the increasing pressure in the stomach. 2) In gastroesophageal reflux disease (GERD), the cardia cannot withstand the pressure and subsequently opens. Depending on the degree of insufficiency of the LES and the force applied during provocative test, angular deformity of the stomach appears, due to the shortening of LES as well as a downsizing of the gas bubble in the stomach; 3) Pyloric sphincter (PS) is a true sphincter. Evacuation from the stomach is the result of the opening of the PS due to increase of antral pressure above the "threshold" level; 4) The evacuation starts in the upright position, when the liquid chyme above PS creates hydrostatic pressure above the threshold; 5) When hydrostatic pressure is reduced below the threshold level or in the recumbent position the antral pressure is created by the clamping of deep peristaltic wave and formation of the closed antral cavity; 6) The portioned evacuation is provided in two ways; а) the volume of antral cavity corresponds to the volume of duodenal bulb; b) in upright position after filling of the duodenal bulb the postbulbar sphincter is closed, whereby the pressure in the bulb rises, which leads to a reflex contraction of the PS and cessation of the e stomach emptying.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>физиология желудка</kwd><kwd>нижний пищеводный сфинктер</kwd><kwd>луковица двенадцатиперстной кишки</kwd><kwd>гипотеза</kwd><kwd>двигательная функция</kwd><kwd>пилорический сфинктер</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gastric physiology</kwd><kwd>lower esophageal sphincter</kwd><kwd>duodenal bulb</kwd><kwd>hypothesis</kwd><kwd>motor function</kwd><kwd>pyloric sphincter</kwd><kwd>stomach</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Törnblom H, Simrén M, Abrahamsson H.
