Anatomy

Right ventricle

Isolated anatomical view of the right ventricle, the lower right chamber of the human heart. It is a muscular reddish-brown to pink-red chamber with walls thicker than the atria but thinner than the left ventricle. The chamber appears broad and triangular in front view and crescentic to triangular in cross-section, with a rounded anterior contour and a broad curved internal cavity. It forms much of the anterior surface of the heart, tapers toward the apex, and includes an inlet from the tricuspid orifice and a broad conical outflow region leading toward the pulmonary trunk. The internal surface is rough with coarse trabeculations or muscular ridges, while the outer surface is smooth.
