Question

Why is the left ventricular wall of the heart thicker than the right ventricular wall?

• A. To accommodate a greater volume of blood
• B. To expand the thoracic cage during diastole
• C. To pump blood with greater pressure
• D. To pump blood through a smaller valve

Answer 1

The correct option is C

To pump blood with greater pressure

The left ventricle has thicker walls than the right because it needs to pump blood to the rest of the body while the right ventricle pumps blood only to the lungs.
