Correct answer
Explanation
The sphygmomanometer is designed to monitor the blood pressure by measuring the force of the blood in the heart where the pressure is the greatest. This occurs during the contraction of the ventricles when blood is pumped from the heart to the rest of the body (systolic pressure). The minimal force is also measured during the relaxation of the heart.
