The Wall of the Left Ventricle is Thicker Than the Right

Question

The wall of the left ventricle is thicker than the right ventricle in order to ________.
A) pump blood with greater pressure
B) accommodate a greater volume of blood
C) pump blood through a smaller valve
D) expand the thoracic cage

Accepted Answer

The left ventricle pumps blood to the rest of the body, so it needs to generate greater pressure in order to do so effectively. A thicker wall allows it to generate this pressure.
