What is the term for the pressure exerted by blood against the walls of blood vessels?

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

Answer: (A)

Blood pressure is the force exerted by circulating blood on the walls of arteries. It’s usually shown as systolic over diastolic pressure and measured in millimeters of mercury (mmHg). This pressure comes from the heart’s pumping action and the resistance of the blood vessels, and it tells us how hard the blood is pushing through the circulatory system. Heart rate, on the other hand, is how many times the heart beats each minute. A pulse is the palpable tapping of blood moving through arteries as the heart beats. Hematocrit is the proportion of blood volume that is made up of red blood cells.
