The right ventricle

In the cavity of the right ventricle (ventriculus dexter) distinguish a wide rear section and a narrower front. Anterior is called the arterial cone (conus arterioris) and has a hole that connects it to the pulmonary trunk (truncus pulmonalis). The rear section is connected to the right atrium.

In opening the pulmonary trunk are three semilunar valves protruding into the pulmonary trunk: front, right and left.

Together they form the semilunar valve pulmonary trunk (valva trunci pulmonalis). In the interior of the valve is semilunar valve nodule (nodulus valvulae semilunaris), which departs from the semilunar valve crescent (lunula valvulae semilunaris), which is a tight bundle. On the part of the pulmonary trunk semilunar valves form pockets, which, together with the valves prevent the backflow of blood from the pulmonary trunk to the right ventricular cavity.
