1. The heart is always contracting.
2. Our Cardiovascular System has these nifty one way valves to prevent backflow (SO blood cannot flow backwards only forward.
3. Vasoconstriction vs. Vasodialation. Vasoconstriction is when the arteries and veins in your vascualr system get smaller in radius. Vasodialtion is the opposite. This helps in maintaining accuarate blood pressure.
Without heart contraction, there is no blood pressure

What causes blood to flow through the heart?
The blood flows to and from the heart primarily because of the relaxing and contracting of the heart muscle. Muscles throughout the body also exert pressure on blood vessels to literally push blood to the heart. the relaxing and contracting of the heart muscle
What is the difference between systolic pressure and diastolic pressure?
systolic pressure when ventricals are contracting while during diastole they are in relaxed state
What pressure does the action of the heart create in the blood vessels?
Blood pressure is the measure of the pressure created as the heart pumps blood through the blood vessels. This is one of the most important vital signs.
How are heart contractions and blood pressure related?
Yes. The top number which is called Systolic is the pressure on the arteries when the heart is contracting. The bottom number which is called Diastolic, is the pressure on the arteries when the heart is relaxed. If you were to feel your pulse, it has a rhythm. When you feel the heart is contracting. The heart is relaxing between the beats.
What is measured when taking a persons blood pressure?

When heart isn't beating what's the blood pressure?

What do the 2 numbers in blood pressure represent?
The first number in a blood pressure reading is the systolic blood pressure. It represents the pressure in the artery when the heart is contracting. The second number is the diastolic blood pressure, and represents the pressure when the heart is relaxing.
Explain why blood pressure is expressed with two numbers?
Diastolic: Referring to the time when the heart is in a period of relaxation and dilatation(expansion). Systolic: The blood pressure when the heart is contracting. Measuring the pressure into and out of the heart.
When measuring blood pressure what does 201 over 80 mean?
It means that the pressure in your arteries is enough to push mercury 80 millimeters up a tube when your heart is not contracting, and 201 millimeters when your heart is contracting. It also means you need to take measures to lower your blood pressure, as this is generally too high in the long run.
Why does th humanbody notcollapseunder the weight of the air pressing down on it?
Due to blood pressure maintained by the heart.
What does the 3 numbers blood pressure reading mean?
The upper reading is the systolic blood pressure while the lower reading is the diastolic blood pressure. Systole is the contraction of the heart while diastole is the relaxation of the heart.
