☛ The pressure at which blood is pumped around the body by the heart is called blood pressure.

The blood pressure of a person is expressed in terms of millimetres of mercury which is written as mm Hg.

➤ Blood pressure in human is always expressed in the form of two values:-

➥ Systolic pressure :-The maximum pressure at which the blood leaves the heart through the main artery (aorta) during contraction phase is called the Systolic pressure.

This high pressure in the main artery maintains a steady flow of blood in all the arteries towards the capillaries.

The normal Systolic pressure's value is 120 mm Hg .

➥ Diastolic pressure :- The minimum pressure in the arteries during the relaxation phase of heart is called the diastolic pressure.

The value of diastolic pressure is always lower than that of the Systolic pressure.

The normal Diastolic pressure's value is 80 mm Hg.
