Solution

The correct option is B
Left ventricle

The interior of the heart is divided into four chambers:

The two upper chambers are the atria, which have thin walls and receive blood from the veins.

The two lower chambers are the ventricles, which have thick walls and force blood out of the heart by way of arteries. The left ventricle has the thickest walls because it is the major pumping chamber of the heart.
