Blood pressure is pressure exerted by blood on the walls of blood vessels.
The two numbers represent the systolic and diastolic pressure. Systolic pressure is the pressure exerted during ventricular contraction(also called systole) and diastolic pressure is the pressure exerted during ventricular relaxation(also called diastole).
The units of blood pressure are millimeters of Mercury (mmHg) because it represents how far up a tube the pressure can push a column of Mercury, which was how pressure used to be measured.

Why blood pressure is expressed with two number?
When a blood vessel (like an elastic pipe) is empty there is no pressure on its wall. When there is blood flowing in a blood vessel it exerts pressure on the walls of the blood vessel (pipe). This is the basal pressure called the Diastolic pressure (The lower of the two numbers). When the heart pumps blood it drives the blood with force and this exerts higher pressure on the walls of the blood vessel. This is called the Systolic pressure, the higher number in the blood pressure measurement. Thus, Blood Pressure of 120/70 means the systolic pressure is 120 and the diastolic pressure is 70.
What does the 3 numbers blood pressure reading mean?
A blood pressure reading consists of two numbers: systolic pressure (the top number) and diastolic pressure (the bottom number). The systolic pressure measures the pressure in the arteries when the heart beats, while the diastolic pressure measures the pressure in the arteries when the heart is at rest between beats. The third number, if present, is the pulse pressure, calculated by subtracting the diastolic pressure from the systolic pressure. This number gives an indication of the force the heart generates with each contraction.
What do blood pressure readings mean?
The top number in the blood pressure fraction is the Systolic pressure, or the amount of pressure put on the walls of the arteries during the contraction and ejection of blood from the left ventricle. The bottom number is called the Diastolic Pressure and it means the lowest pressure in an artery in the moments between beats when your heart is resting.
What are the two blood pressure measures called?
Blood pressure is the amount of blood per section of your blood vessels. You have two different readings because blood pressure varies; for example, your blood pressure is higher after heavy exercise due to the fact that your heart is pumping blood faster.
Why is there two different types of blood pressure?
If you mean Systemic & Pulmonary, that's because they're separate systems. If you mean systolic & diastolic, then they're not different; they represent highest and lowest pressure of each stroke of the heart.
What is the difference between systolic pressure and diastolic pressure?
systolic pressure when ventricals are contracting while during diastole they are in relaxed state
How does blood pressure effect blood pressure And what number is sount for the high blood pressure . hurry ...?
A blood pressure measures the amount of pressure on your arteries when your heart is pumping and contracting blood. There are two measurements. One is the diastolic. The diastolic is the measurement of the pressure on your arteries when your heart is relaxed. This number should be low, in between 50 and 90. It is the bottom number in the ratio. The systolic measurement is the top number in the ratio. The systolic measurement is the amount of pressure on the arteries when the heart is beating or contracted. This number should be between 100 and 150. The text book normal blood pressure is 120/80=S/D. hope that helps.
What is the force exerted by blood as it moves through the blood vessels?
This is called blood pressure. Blood pressure is measured in two parts. The first number is the systolic blood pressure and this shows the pressure exerted on artery walls when the ventricles contract and pump blood into the arteries and around the body. The second number is the diastolic blood pressure and this shows the pressure in the arteries when the heart is at rest and refilling ready for the next contraction.Blood pressureThis is known as blood pressure. The pressure high is during systole (when the heart pumps blood to the body) and a pressure low during diastole (when the heart is receiving blood back from the body)This is sometimes referred to as arterial pressure and different measurements are made regarding the arterial pressure such as the mean arterial pressure (MAP).
What difference between systolic pressure and diastolic pressure?
Two numbers are used to represent blood pressure. Systolic pressure (the first and larger number of the equation) is the force that the blood flows from the heart into the arteries. Diastolic pressure (the second and smaller number of the equation) is the force as the heart relaxes, allowing the blood to flow back into the heart.
What is your blood pressure?
It is a measure of the pressure of the blood in your arteries at two stages of the heartbeat.
Why are there two different types of blood pressure rather that just one?
There are two types of blood pressure—systolic and diastolic—because they measure different phases of the heart's pumping cycle. Systolic pressure, the higher number, indicates the force of blood against the artery walls when the heart contracts and pumps blood. Diastolic pressure, the lower number, measures the pressure in the arteries when the heart is at rest between beats. Together, they provide a comprehensive view of cardiovascular health and how well the heart and blood vessels are functioning.
When blood pressure is taken the reading is the time of most pressure and the reading is the time of least pressure.?
When blood pressure is measured, it consists of two readings: systolic and diastolic pressure. The systolic pressure, the higher number, represents the pressure in the arteries when the heart beats and pumps blood. The diastolic pressure, the lower number, indicates the pressure in the arteries when the heart is at rest between beats. Together, these readings provide a comprehensive picture of cardiovascular health.
