Blood Pressure or vascular pressure is one of the vital signs that is being measured or checked to assess the patient’s level of physical functioning. Blood pressure starts at the heart.

The pressure of the blood decreases as blood circulates through the blood vessels – arteries, capillaries and veins. Arteries are responsible for carrying the blood away from the heart. Capillaries enable the exchange of water and chemicals between the blood and the tissues, while veins carry blood from the capillaries back to the heart.
