Detailed explanation-1: -Blood pressure is the force of the blood pushing against the artery walls. The force is generated with each heartbeat as blood is pumped from the heart into the blood vessels. The size and elasticity of the artery walls also affect blood pressure.
Detailed explanation-2: -Pressure is a measure of the force that the blood exerts against the vessel walls as it moves the blood through the vessels. Like all fluids, blood flows from a high pressure area to a region with lower pressure. Blood flows in the same direction as the decreasing pressure gradient: arteries to capillaries to veins.
Detailed explanation-3: -Answer and Explanation: The statement (c) Artery walls help to maintain pressure, even between heartbeats is TRUE about blood pressure.
Detailed explanation-4: -Blood pressure is the force of blood against the arteries. An individual should maintain a normal blood pressure from 90 – 120 / 60 – 80 mm Hg. Blood pressure is given by two numbers, with one above or before the other – 120/80.120 – This is called systolic pressure and 80 – This is called diastolic pressure.
