Which term denotes the force of circulating blood on vessel walls?

• A. Aorta
• B. Blood pressure
• C. Signs of phlebitis
• D. Varicose veins

Answer: (B)

Blood pressure is the force that circulating blood exerts on the walls of blood vessels as the heart pumps and pushes blood through the arteries. It reflects the pressure during the heartbeat (systolic) and between beats (diastolic), and it depends on how forcefully the heart contracts as well as how easy or resistant the vessels are to blood flow. Among the options, this term best describes the force in question. The aorta is a major vessel, not the force itself. Signs of phlebitis refer to vein inflammation, and varicose veins describe swollen veins due to valve failure—both are conditions, not the force. Blood pressure is commonly measured in millimeters of mercury and is a key indicator of cardiovascular function.
