Right Ventricle

The right ventricle is one of the four chambers of the heart. The right ventricle is connected to the right atrium, from which it receives deoxygenated blood through the tricuspid valve. It contracts during sistole to pump the blood out into the pulmonary artery through the pulmonary valve and pulmonary trunk. The right ventricle is triangular in shape, extending from the right atrium to near the apex of the heart.

The heart is divided into four chambers: two atria, which are situated in the upper half of the heart, right and left atria; and two ventricles, right and left. The ventricles are not connected to one another but to their respective atrium. The right ventricle is located in the lower right quarter of the heart and is separated from the left ventricle by the interventricular septum.
