Blood pressure:

It is the force that blood exerts against the wall of a vessel. Their pressure is much greater in arteries the in veins.

It is measured by using as instruments called sphygmomanometer.

The pressure of blood inside artery during contraction or ventricular systole is called systolic pressure and pressure in artery during relaxation or ventricular diastole Is called diastolic pressure. The normal systolic pressure is about 120 mm of Hg and diastolic pressure is 80 mm of HG.
