Noun
1. the pressure of the circulating blood against the walls of the blood vessels; results from the systole of the left ventricle of the heart; sometimes measured for a quick evaluation of a person's health; "adult blood pressure is considered normal at 120/80 where the first number is the systolic pressure and the second is the diastolic pressure"
(hypernym) vital sign
(hyponym) systolic pressure
(part-holonym) circulation
Blood pressure Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
Blood pressure (BP), sometimes referred to as arterial blood pressure, is the pressure exerted by circulating blood upon the walls of blood vessels, and is one of the principal vital signs. When used without further specification, "blood pressure" usually refers to the arterial pressure of the systemic circulation. During each heartbeat, blood pressure varies between a maximum (systolic) and a minimum (diastolic) pressure. The blood pressure in the circulation is principally due to the pumping action of the heart. Differences in mean blood pressure are responsible for blood flow from one location to another in the circulation. The rate of mean blood flow depends on the resistance to flow presented by the blood vessels. Mean blood pressure decreases as the circulating blood moves away from the heart through arteries and capillaries due to viscous losses of energy. Mean blood pressure drops over the whole circulation, although most of the fall occurs along the small arteries and arterioles. Gravity affects blood pressure via hydrostatic forces (e.g., during standing), and valves in veins, breathing, and pumping from contraction of skeletal muscles also influence blood pressure in veins.

EUFIC Nutrition Glossary
The pressure exerted by the circulating blood on the walls of arteries and veins and in the heart chambers. When the heart contracts, the maximum pressure exerted is the systolic pressure; during relaxation, the minimum pressure is the diastolic.

Aging Hearts and Arteries Glossary
The force that flowing blood exerts against artery walls. Systolic blood pressure occurs when the heart contracts and pumps blood into the aorta. Diastolic blood pressure occurs when the aortic valve closes and the heart relaxes and refills with blood.

High Blood Pressure
Blood pressure is the amount of force exerted by the blood against the walls of the arteries. Usually, blood pressure is expressed in two numbers, such as 120/80, and is measured in millimeters of mercury (mm Hg).
Dictionary of Medicine (Shahram)
The blood pressure is the pressure of the blood within the arteries. It is produced primarily by the contraction of the heart muscle. It's measurement is recorded by two numbers. The first (systolic pressure) is measured after the heart contracts and is highest. The second (diastolic pressure) is measured before the heart contracts and lowest. A blood pressure cuff is used to measure the pressure. Elevation of blood pressure is called "hypertension." (see hypertension).
Lung Diseases Glossary
The pressure of blood against the walls of a blood vessel or heart chamber. Unless there is reference to another location, such as the pulmonary artery or one of the heart chambers, it refers to the pressure in the systemic arteries, as measured, for example, in the forearm.

Hepatitis Central (TM) Liver Disease Medical Glossary
A measure of how well blood circulates through your arteries, listen in the format of the systolic pressure over the diastolic pressure. Normal blood pressure is about 120/80
NDIC Diabetes Dictionary
the force of blood exerted on the inside walls of blood vessels. Blood pressure is expressed as a ratio (example: 120/80, read as "120 over 80"). The first number is the systolic (sis-TAH-lik) pressure, or the pressure when the heart pushes blood out into the arteries. The second number is the diastolic (DY-uh-STAH-lik) pressure, or the pressure when the heart rests.

Diabetes Glossary
The force of the blood on the walls of arteries. Two levels of blood pressure are measured-the higher, or systolic pressure, which occurs each time the heart pushes blood into the vessels, and the lower, or diastolic, pressure, which occurs when the heart rests. In a blood pressure reading of 120/80, for example, 120 is the systolic pressure and 80 is the diastolic pressure. A reading of 120/80 is said to be in Sthe normal range.
