Answer 1

Answer:

A sphygmomanometer is a device that measures blood pressure. ... A stethoscope is used to listen to arterial blood flow sounds. As the heart beats, blood forced through the arteries cause a rise in pressure, called systolic pressure, followed by a decrease in pressure as the heart's ventricles prepare for another beat.
