The pressure exerted by the blood against the walls of blood vessels is called?

• A. Pulse
• B. Blood pressure
• C. Respiratory rate
• D. Temperature

Answer: (B)

The pressure exerted by the blood against the walls of blood vessels is blood pressure. This reflects the force produced by the heart as it pumps (cardiac output) and the resistance offered by the vessels. It’s measured as systolic pressure (the pressure during heart contraction) over diastolic pressure (the pressure when the heart rests), in millimeters of mercury (mmHg). Pulse, on the other hand, is the tactile sensation of arterial expansion with each heartbeat—not a direct measure of the pressure itself. Respiratory rate is how fast you’re breathing, and temperature is a measure of body heat. That’s why blood pressure is the correct term here.
