What are two physical forces that cause blood pressure?

Answer 1

Two physical forces that cause blood pressure are cardiac output and vascular resistance. Cardiac output refers to the volume of blood the heart pumps per minute, which increases blood pressure when elevated. Vascular resistance, on the other hand, is the opposition to blood flow within the blood vessels, primarily influenced by the diameter of the arteries; narrower vessels increase resistance and subsequently raise blood pressure. Together, these forces determine the pressure exerted by circulating blood on the walls of the arteries.
