Blood pressure is the force exerted by the blood on the walls of the arteries as it gushes through it the force originates from the pumping motion of the heart. It can also be described as the effort it takes for the heart to pump blood throughout the body the measuring of blood pressure is also based on this same aspect.

It is measured in two stages, the first when the heart pumps the blood known as the systolic pressure and the second when the heart again fills up with blood known as the diastolic pressure expressed in the form of a ratio for example a reading of 120/ 80 mm Hg is said to be normal where the higher figure indicates the systolic pressure and the lower figure indicates the diastolic.

It is typically higher in the morning and lower at night though when it gives a consistently high reading (about 140/90 mm Hg) the condition is known as high blood pressure or hypertension.

Blood pressure is the force exerted by blood onto the inside of a blood vessel, most commonly an artery. The artery from which blood pressure is measured are the largest, easily accessible ones that deliver blood top the rest of the body with the exception of the vessels that carry blood to the lungs. Universally measured in millimetres of mercury (mmHg), it is taken as two readings, the systolic and the diastolic. Systolic blood pressure is defined as the peak pressure within the arteries during a cardiac cycle. Diastolic blood pressure is when the pressure is at its lowest (most relaxed), during the cycle.
High blood pressure is called hypertension, low is hypotension.
Every individual will have their own blood pressure and there are many considerations to be taken into account before appropriate treatment can be prescribed.
