Introduction: the right ventricle forms the largest part of the sternocostal surface of the heart, a small paiof the diaphragmatic surface and almost the entire inferior border of the heart.
Features: the walls of the right ventricle is thicker than those of the artrium. The inferior is thrown into a series of muscular ridges, the trabeculae carnae.
The moderator band (septomarginal trabecula) is a muscular bundle crossing the ventricular cavity from the interventricular  septum to the anterior wall. It is of importance because it conveys the right branch of the atrioventricular  bundle to the ventricular muscle.
The tricuspid valve guard the right atrioventricular  orifice. It has three cusps. Anterior,  posterior and septal and are attached by their bases to the fibrous atrioventricular  ring. The edge and ventricular surfaces if the cusps are attached to the chordae tendinae which project from the papillary muscles and prevent the cusps from being everted when the ventricle contracts.
The infidibulum is a funnel-shaped structure between the artrioventricular  and pulmonary orifice. It is thin and smooth and lack trabeculae carnea.
Function: the right ventricle receives blood from the right atrium through the right atrioventricular  orifice. This blood is pumped through the pulmonary trunk and pulmonary arteries to the lungs.
