The picture below accurately depicts a healthy heart. The left ventricle has a thicker myocardium than the right. What best explains why the muscle in the left ventricle is larger than the one on the right?
A. The left ventricle pumps blood to the systemic circulation process, while the right ventricle pumps blood to pulmonary circulation.
B. The right ventricle pumps blood to the systemic circulation process, while the left ventricle pumps blood to pulmonary circulation.
C. The right ventricle directly pumps blood into the left ventricle, which then pumps the blood to the entire body.
D. The left ventricle is pumping oxygen-poor blood, so the muscle is not getting enough oxygen.
