High blood pressure, or hypertension is a common condition in which the force of blood on the walls of your arteries is often too high. Arteries are the blood vessels that carry blood away from your heart to supply your tissues with oxygen and nutrients. In your heart, two chambers, called ventricles,contract with each heartbeat to push blood to your lungs and through your arteries to your body. 

As blood flows through them, three main factors affect the pressure on your artery walls. The first is cardiac output,or the amount of blood your ventricles push out of your heart each minute. Your blood pressure goes up as cardiac output increases. The second factor affecting your blood pressure is blood volume,or the total amount of blood in your body. Blood pressure also goes up as blood volume increases. The third factor that affects your blood pressure is resistance,which is anything working against the blood flow through your arteries. Several factors contribute to resistance. 

One resistance factor is the flexibility of your artery wall. Healthy arteries expand with each heart beat to help reduce blood pressure on the wall. Another resistance factor is the diameter of your arteries. Your body is able to increase the diameter of your arteries to lower your blood pressure,or reduce the diameter to raise your blood pressure. A third resistance factor is blood viscosity, or thickness. In your blood, more particles, such as proteins and fat, increase viscosity. If your blood is thicker, your blood pressure goes up as your heart works harder to push it through your arteries. 

Your blood pressure can be measured with a device called a sphygmomanometer, or blood pressure cuff. When your heart beats,the pressure of blood on the walls of your arteries is called systolic pressure. When your heart relaxes between beats,pressure on the artery wall is called diastolic pressure. While your blood pressure may change throughout the day,it should normally be less than 120 millimeters of mercury for systolic pressure,and less than 80 millimeters of mercury for diastolic pressure. If your systolic pressure frequently stays above 140,or your diastolic pressure frequently stays above 90,you have high blood pressure. Over time, high blood pressure will damage the walls of your arteries. Your artery wall may become weak and form an enlargement called an aneurysm. Or the wall may burst and bleed into the surrounding tissue. Small tears in your artery wall may attract certain substances in your blood,such as cholesterol, fat, and calcium,to form a build-up called a plaque. Blood flow through your artery decreases as the plaque enlarges.
