Blood passes through the ostium atrioventriculare sinistrum from the left atrium into the left ventricle. The ostium atrioventriculare can be closed by the valva atrioventricularis sinistra. In addition, the left ventricle has an inflow and outflow tract. The inflow runs along the posterior wall, the left lateral wall and the apical section. The smooth-walled outflow path is located near the Septum interventriculare and continues into the Vestibulum aortae. It consists mainly of muscles (pars muscularis). The opening between the aortic outflow path of the left ventricle and the aorta is called the ostium aortae. The wall of the left ventricle is about three times as thick as that of the right ventricle and is therefore part of the high-pressure system.
