1. Blood pressure
The pressure of blood in a blood vessel: * arterial pressure: 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.

2. Blood pressure (systolic blood pressure, diastolic blood pressure)
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.
