Final answer:

High heart rate results in rapid contraction of the left ventricle, allowing efficient blood pumping to meet increased oxygen demand.


Explanation:

When the heart rate is very high, the left ventricle is contracting rapidly. This rapid contraction allows the heart to pump more blood to the body efficiently due to the increased demand for oxygen during high heart rates. Electrical impulses generated in the heart cause the atria and ventricles to contract in a coordinated manner to maintain blood flow.
