    Cardiovascular System
    Why is the myocardium of the left ventricle thicker than that of the right ventricle?
    The length of the blood vessels that make up the systemic circuit is much greater than the length of vessels in the pulmonary circulation. This greater length presents a greater resistance to the flow of blood. So the LV must be stronger – made of thicker muscle – to exert sufficient pressure on the blood to overcome the resistance.
