Question

PLEASE HURRY TEST IS TIMED!!!

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.

Answer 1

Answer- A: The left ventricle of your heart is larger and thicker than the right ventricle. This is because it has to pump the blood further around the body (systemic circulation), and against higher pressure, compared with the right ventricle that does pulmonary circulation.

Answer 2

The correct option is A.

A. The left ventricle pumps blood to the systemic circulation process, while the right ventricle pumps blood to pulmonary circulation.

Step-by-step explanation:

Th heart has two ventricles, left ventricle and right ventricle. The right ventricle has thinner myocardium as compared to left ventricle, as it pumps deoxygenated blood to the lungs, so it can gain back its oxygen. Left ventricle has thicker myocardium, as it pumps oxygenated blood to all over the body, commonly known as the systemic circulation.
