  MedlinePlus Medical Encyclopedia: Blood pressure
Blood pressure is a measurement of the force applied to the walls of the arteries as the heart pumps blood through the body.
The pressure is determined by the force and amount of blood pumped, and the size and flexibility of the arteries.
Blood pressure is usually measured while you are seated with your arm resting on a table.

  High blood pressure (hypertension) - causes, treatments and medications
Arteries are vessels that carry blood from the pumping heart to all the tissues and organs of the body.
Normal blood pressure is below 120/80; blood pressure between 120/80 and 139/89 is called "pre–hypertension", and a blood pressure of 140/90 or above is considered high.
An elevation of the systolic and/or diastolic blood pressure increases the risk of developing heart (cardiac) disease, kidney (renal) disease, hardening of the arteries (atherosclerosis or arteriosclerosis), eye damage, and stroke (brain damage).

  High Blood Pressure (Hypertension)
Blood pressure is the pressure the blood exerts against the blood vessel walls as the heart pumps.
Blood pressure is driven by two physical forces - the one from the heart as it pumps blood into the arteries and through the circulatory system, and the other from the arteries as they resist this blood flow.
Blood pressure is measured as air is gradually let out of the cuff, which allows blood to flow through the artery again.

  Blood pressure - Wikipedia, the free encyclopedia
Blood pressure is the pressure exerted by the blood on the walls of the blood vessels.
The systolic pressure is defined as the peak pressure in the arteries during the cardiac cycle; the diastolic pressure is the lowest pressure (at the resting phase of the cardiac cycle).
Venous pressure is the blood pressure in a vein or in the atria of the heart.

 Hypertension (High Blood Pressure)
Blood pressure is the pressure your blood exerts against your blood vessel walls as your heart pumps.
Blood pressure is measured as air is gradually let out of the cuff, which allows blood to begin to flow through the artery again when the blood pressure in the artery is greater than the pressure in the cuff.

 Taking a blood pressure
Blood pressure varies relative to heart's pumping of blood.
The highest pressures occur during systole as blood is ejected into the aorta and subsequent arteries of the body.
When you apply a pressure of 180mm Hg to the arm, the 120mm of pressure from the artery cannot overcome your externally applied pressure; the artery stays shut.

 Blood pressure
Note: Blood pressure is measured in millimeters of mercury or andldquo;mm Hg.andrdquo;.
The higher number is called the systolic pressure and is the pressure exerted on artery walls when the heart is in the contracting phase.
The lower number is the diastolic pressure and is the pressure exerted on artery walls when the heart is in the resting phase.

 Blood pressure: information about, high blood pressure, symptoms of high blood pressure, risks of high blood pressure
Blood pressure is the force created by the heart as it pushes blood into the arteries and the circulatory system.
If high blood pressure is left unchecked, it can cause blood vessels in the kidneys to become thickened and narrowed, possibly leading to reduced blood supply and reduced kidney function.
It controls the expansion and contraction of blood vessels, and thus blood pressure, by regulating the amount of nitric oxide to which the vessels are exposed.

 Blood pressure
Blood pressure readings are usually given as 2 numbers: for example, 110 over 70 (written as 110/70).
The first number is the systolic blood pressure reading, and it represents the maximum pressure exerted when the heart contracts.
The second number is the diastolic blood pressure reading, and it represents the pressure in the arteries when the heart is at rest.

Blood pressure is a measure of the force of blood inside an artery.
A blood pressure measurement is taken by temporarily stopping the flow of blood in an artery (usually by inflating a cuff around the upper arm) and then listening for the sound of the blood beginning to flow through the artery again as air is released from the cuff.
These two pressures are expressed in millimeters of mercury (mm Hg) because the original devices that measured blood pressure used a column of mercury.

The pressure would cause the garden hose to explode and that is what happens to a blood vessel too small for the pressure going through it.
