Right ventricle
Extracted from the Wikipedia article Ventricle (heart).
Shape
The right ventricle is triangular in shape and extends from the tricuspid valve in the right atrium to near the apex of the heart. Its wall is thickest at the apex and thins towards its base at the atrium. When viewed via cross section however, the right ventricle seems to be crescent shaped. The right ventricle is made of two components: the sinus and the conus. The Sinus is the inflow which flows away from the tricuspid valve. Three bands made from muscle, separate the right ventricle: the parietal, the septal, and the moderator band. The moderator band connects from the base of the anterior papillary muscle to the ventricular septum.
