This is called blood pressure. It is measured using a sphygmomanometer and is expressed in a fraction format. For example, a normal BP is considered to be 120/80. The top number is the systolic pressure, which is the pressure exerted on the blood vessels during a heart beat. The lower number, diastolic pressure, is the pressure when the heart is at rest. The difference between these numbers (40) is the pulse pressure. This is the pressure your heart is actually creating, or how hard it is working.

Why are blood vessels elastic?
Blood vessels are elastic in order to maintain the circulatory system. The vessels need to be able to stretch based on the force of the blood that is pumped through them. There are also receptors on blood vessels that control the diameter in order to shift blood to other parts of the body.
How do calculate pulse rate?
Blood pressure is the force or pressure that blood puts on the walls of your arteries as it goes through your body. Blood Pressure readings are usually written as 2 numbers. The first and higher number is called systolic pressure. It is the pressure in your blood vessels when your heart beats. The second and lower number is called the diastolic pressure. It is the pressure in your blood vessels when your heart is resting between beats.
What prevent blood from flowing backward in blood vessels?
veins have valves in them that prevent backflow
Which organs uses force to move blood?
The heart is a double pump. It pumps and forces blood through the chambers and blood vessels.
Why are red blood cells called Blood's Work Force?
Red blood cells are responsible for carrying oxygen to the blood vessels spanning the whole body and eventually to the organs. Therefore, they are called the blood's work force.
Primary force that moves blood?
The heart is the primary force that moves blood through the body. As the heart contracts and releases the blood is then pumped through the vessels that travel to all areas of the body.
