What Is HTN? What are the symptoms of hypertension?

Hypertension, also known as high or increase blood pressure, is a situation in which the blood vessels have persistently raised pressure. Blood is carried from the heart to all corridor of the body in the vessels. All time the heart beats, it pumps blood into the vessels. Blood pressure is created by the force of blood pushing against the walls of blood vessels ( highways) as it's pumped by the heart. The advanced the pressure, the harder the heart has to pump.
