Everyone has blood pressure.
Blood pressure is the forward thrust of the blood against the walls of the arteries in the body.
This thrust is produced by the heart as it pumps or beats. It keeps blood moving through the arteries-the blood vessels that carry blood from the heart to all parts of the body. The walls of the arteries are elastic and muscular. They stretch and contract to take the variations of blood flow and force. Each time the heart contracts, blood pressure in the arteries increases.
