how does high blood pressure affect the circulatory system?

High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause: Chest pain, also called angina.

High blood pressure, or hypertension, occurs when your blood pressure increases to unhealthy levels. Your blood pressure measurement takes into account how much blood is passing through your blood vessels and the amount of resistance the blood meets while the heart is pumping. Narrow arteries increase resistance.

Left undetected (or uncontrolled), high blood pressure can lead to: Heart attack — High blood pressure damages arteries that can become blocked and prevent blood flow to the heart muscle. Stroke — High blood pressure can cause blood vessels in the brain to clog more easily or even burst.

Your heart rate can increase without any change occurring in your blood pressure. As your heart beats faster, healthy blood vessels will expand in size to allow increased blood flow, which helps your blood pressure remain relatively stable.

If blood pressure is too high for too long, it can cause serious damage to the blood vessels. This damage can result in a range of complications, some of which can be life threatening. They include heart failure, vision loss, stroke, kidney disease, and other health problems.

But even without symptoms, high blood pressure can cause damage to your blood vessels and organs, especially the brain, heart, eyes, and kidneys. Early detection is important. Regular blood pressure readings can help you and your doctor notice any changes.

High blood pressure means the pressure inside the blood vessels (called arteries) is too high. As the heart pumps against this pressure, it must work harder. Over time, this causes the heart muscle to thicken. Because there are often no symptoms with high blood pressure, people can have the problem without knowing it.
1378762
High blood pressure results from the tightening of very small arteries called arterioles. Arterioles regulate the blood flow through your body. As these arterioles tighten (or constrict), your heart has to work harder to pump blood through the smaller space, and the pressure inside the vessels grows.

Uncontrolled high blood pressure can result in hardening and thickening of your arteries, narrowing the channel through which blood can flow. High blood cholesterol levels. High levels of cholesterol in your blood can increase the risk of formation of plaque and atherosclerosis.
1008097
The nervous system automatically increases the heart rate to get the blood pumping. Meanwhile, the blood pressure drops a bit because the force of blood moving through the veins is lower.
256504
High blood pressure, also called hypertension, is dangerous because it makes the heart work harder to pump blood out to the body and contributes to hardening of the arteries, or atherosclerosis, to stroke, kidney disease, and to heart failure.

Your blood pressure is a reading of the force with which blood is passing through your circulatory system. Blood pressure changes naturally many times a day. Most changes are normal and predictable. When these spikes and valleys in your blood pressure occur, you may not experience unusual signs or symptoms.

If your blood pressure is too high, it puts extra strain on your blood vessels, heart and other organs, such as the brain, kidneys and eyes. Persistent high blood pressure can increase your risk of a number of serious and potentially life-threatening health conditions, such as: heart disease. heart attacks.

Heart problems. High stress levels can raise your blood pressure and heart rate. Over time, high blood pressure can cause serious health problems, such as stroke and heart attacks. Younger women with a history of heart problems especially may be at risk of the negative effects of stress on the heart.

High blood pressure can cause many complications. High blood pressure (hypertension) can quietly damage your body for years before symptoms develop. Uncontrolled high blood pressure can lead to disability, a poor quality of life, or even a fatal heart attack or stroke.

How serious is high blood pressure? Early on, you may not notice symptoms of high blood pressure, so you may not be too concerned. However, in the long run high blood pressure can kill you. Normally, your heart beats regularly, pumping blood through the vessels all over your body.
