Why is the left ventricle more muscular than the right ventricle?
A) The left ventricle is supplied with more coronary vasculature so it hypertrophies over time, whereas the right ventricle receives less blood so it atrophies over time. B) The left ventricle must generate enough force to propel blood through the systemic circuit, whereas the right ventricle must generate only enough force to propel blood the short distance from the heart to the lungs in the pulmonary circuit. C) The left ventricle pumps a higher volume of blood to the systemic circuit than the volume of blood the right ventricle pumps to the pulmonary circuit. D) The left ventricle began forming earlier in development so it grew larger than the right ventricle. E) The left ventricle supplies blood to the brain and vital organs so it must be more reliable than the right ventricle which supplies blood to the limbs.
