The Right Ventricle ________

Question

The right ventricle ________.
A) has thinner muscular walls than does the left ventricle
B) receives blood from the left atrium through the right atrioventricular (tricuspid) valve
C) pumps blood out of the heart to the systemic circuit
D) pumps blood out of the heart through the aortic valve
E) is connected to the pulmonary veins

Accepted Answer

The right ventricle has thinner muscular walls than the left ventricle, as it pumps blood to the lungs which have lower resistance than the systemic circuit. This difference in thickness is why the left ventricle is able to generate a higher pressure to pump blood throughout the body.
