heart right ventricle weight to left ventricle weight ratio heart right ventricle weight to left ventricle plus septum weight ratio 2019-12-09T15:21:48Z A calculated value which compares the weight of the right ventricle, the lower chamber of the right side of the heart, which pumps venous blood through the pulmonary trunk and arteries to the capillaries of the lung, with the weight of the left ventricle (including the ventricular septum), the lower chamber of the left side of the heart, which pumps oxygenated blood out through the aorta to all the tissues of the body, and presents it as a ratio.
