WordNet Dictionary
	Definition:		[n]  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"
	See Also:		arterial pressure, circulation, diastolic pressure, force per unit area, pressure, pressure level, systolic pressure, venous pressure, vital sign
Medical Dictionary
	Definition:		The pressure of the blood in the main arteries which rises and falls as the muscles of the body cope with varying demands (e.g. exercise, stress, sleep). There are two types of pressure that are measured: 1) systolic pressure, created by the contraction of the heart muscle pushing blood into the vessels, and 2) diastolic pressure, when the heart is at rest between beats. A reading of 120/80 is said to be the normal range. Blood pressure that is too high (hypertension) can cause health problems such as heart attacks and strokes.
Biology Dictionary
	Definition:		The pressure of blood in a blood vessel: arterial presssure: systolic pressure is the peak pressure during each heart cycle. Diastolic pressure is the minimum pressure during each heart cycle. the mean arterial pressure: is the average pressure throughout the entire cardiac cycle. the pulse pressure: the difference between the systolic and diastolic pressures. venous pressure: central venous pressure is the blood pressure at the entrance of the superior vena cava into the right atrium of the heart. 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 the normal range. Blood pressure that is too high can cause health problems such as heart attacks and strokes.
