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.
systolic pressure when ventricals are contracting while during diastole they are in relaxed state
A blood pressure test measures two values: systolic and diastolic pressure, expressed in millimeters of mercury (mm Hg). The systolic pressure, the higher number, indicates the pressure in the arteries when the heart beats, while the diastolic pressure, the lower number, reflects the pressure when the heart is at rest between beats. For example, a reading of 120/80 mm Hg is considered normal. Blood pressure categories range from normal to hypertension, with readings above 130/80 mm Hg indicating elevated blood pressure.
The measurement of blood pressure results in two numbers: the systolic blood pressure and diastolic blood pressure. This is expressed as a fraction: systolic over diastolic. The diastolic blood pressure is produced when the heart is in a relaxed state. It is the measure of the pressure exerted on the arteries during diastole, or relaxation.
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.
The two reading notes on a blood pressure reading is systolic and diastolic. Systolic reads the pressure in the arteries when the heart muscle beats or contracts. Diastolic reads the pressure in the arteries between beats or contractions.
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.
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.
Any number that can be expressed as the ratio of two integers is a rational number.
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.
A number that cannot be expressed as the ratio of two integers is known as an irrational number.
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.
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.
