What term describes the rhythmic throbbing of arteries as blood is propelled through them?

• A. Heart rate
• B. Pulse
• C. Blood pressure
• D. Circulation

Answer: (B)

Pulse describes the rhythmic throbbing you feel in arteries as the heart pumps blood through them. Each heartbeat sends a surge of blood into the arteries, producing that regular pulsing sensation that you can detect at accessible sites like the wrist or neck. The pulse rate is how many of these throbs occur each minute and often corresponds to the heart rate, but the term pulse specifically refers to the palpable rhythm. Blood pressure is the force of blood against arterial walls, not the rhythmic sensation, and circulation is the overall movement of blood through the body, not the distinct throbbing you feel. So the rhythmic throbbing described is the pulse.
