Explanation:

The pulse is related to the heart's function. A sudden increase in body temperature (fever) is not the pulse. A sudden surge of energy is not the pulse. The process of breathing in and out is respiration. The electrical activity of the brain is measured by an electroencephalogram (EEG). The pulse is the rhythmic beating of the heart that circulates blood.

Answer:

A rhythmic beating of the heart, which is responsible for circulating blood throughout the body.
