In a human body when the heart beats it pumps blood throughout the body for the supply of oxygen and energy. The blood while circulating exerts pressure on the walls of blood vessels.
This pressure is your blood pressure (BP) or arterial blood pressure. It is usually expressed as 2 numbers systolic and diastolic pressure and is expressed in 120/80 mm Hg (millimeters of mercury) which is normal BP for an adult.
The top number is referred to as systolic which is usually the greater amongst the two numbers and measures the arterial pressure during heart muscle contraction.
The lower one is referred to as diastolic which is smaller amongst the two and measures the arterial pressure when the heart muscle rests and refills with blood.
Blood Pressure can vary depending upon the activities, situations, ailments and is under regulation by the endocrine and nervous systems.
If blood pressure is medically low it is referred as hypotension and if it is medically high then it is referred as hypertension. In many cases Hypertension and hypotension go unnoticed because of negligence.
