Why is the myocardium of the right ventricle (RV) thinner than that of the left ventricle (LV)? A. the RV pumps into the pulmonary circuit which has less resistance than the systemic circuit. B. the RV pumps a smaller volume of blood than the LV. C. the RV pumps blood out with a slower exit speed than the RV. D. the RV chamber has a smaller volume than the LV.
Option A. The right ventrical pumps in opposition to a lesser resistance, it does now no longer want to be as muscular as left ventrical.
