Dictionary: Left Ventricle

Left ventricle (VEN-trih-kul): one of the four chambers of the heart. The left ventricle pumps blood full of oxygen out to the body.

Two diagrams show the position of the heart in the body and a close-up, cross section of a healthy heart. Blood flows from the left atrium into the left ventricle and through a valve into the aorta.
