Explain why it is more efficient for contraction of the
ventricles to begin at the apex of the heart than at the base.

Heart may be defined as the important organ of the body that pumps the blood in the whole body. Human heart is divided into four chambers and follows the double circulation.

The heart apex is the bottom part and its base lies on the top. The blood flow in the apex is in the upward direction. The upward direction is against the motion of the gravity. The more pressure is required to move the objects against the gravity and hence, the maximum force is observed at the apex that causes ventricles at the apex.

Bones of the leg, ankle and foot: There are 62 lower extremity bones. They consist of 10 hip and leg, 14 ankle and 38 foot bones. The 10 hip and leg bones are the innominate or hip bone (fusion of the ilium, ischium, and pubis), femur, tibia, fibula, and patella (kneecap) on each side.
