Left ventricle

Other Terms: Left ventricle of heart, Ventriculus sinister, Ventriculus cordis sinister, Ventricule gauche, Linker Ventrikel, VentrĂ­culo izquierdo

Description

The left ventricle is longer than the right. Its cavity is narrower and more circular in cross-section. It forms the apex of the heart and constitutes most of the posterior surface of the heart. Its walls are three times thicker then those of the right ventricle, being thickest near the base and thinnest at the apex. This is because the left ventricle pumps oxygenated blood throughout the entire body while the right ventricle only pumps deoxygenated blood to the lungs. Its trabeculae carneae are arranged like those of the right side, but are smaller and more numerous. The trabeculae at the apex are interlaced. The papillary muscles are for the cusps of the bicuspid valve.
