7. If your instructor asked you to explain why the myocardium is thicker in the left ventricle than it is in the right ventricle, which of the following would you most likely say? a. The right ventricle has to pump harder to overcome the high resistance required to pump blood into the long pulmonary circuit, whereas the left ventricle does not need to generate as much pressure since the systemic circuit is shorter and provides less resistance. b. The right ventricle has to pump harder to overcome the high resistance required to pump blood into the long systemic circuit, whereas the left ventricle does not need to generate as much pressure since the pulmonary circuit is shorter and provides less resistance. c. The left ventricle has to pump harder to overcome the high resistance required to pump blood into the long systemic circuit, whereas the right ventricle does not need to generate as much pressure since the pulmonary circuit is shorter and provides less resistance. d. The left ventricle has to pump harder to overcome the high resistance required to pump blood into the long pulmonary circuit, whereas the right ventricle does not need to generate as much pressure since the systemic circuit is shorter and provides less resistance.
