What blood vessels have the highest pressure?

Important: The highest pressure of circulating blood is found in arteries, and gradu- ally drops as the blood flows through the arterioles, capillaries, venules, and veins (where it is the lowest).

Where is blood pressure the highest?

Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.

What are the 5 Major blood vessels?

There are five classes of blood vessels: arteries and arterioles (the arterial system), veins and venules (the venous system), and capillaries (the smallest bloods vessels, linking arterioles and venules through networks within organs and tissues) (Fig 1).

What is the biggest blood vessel?

The largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.

You need medications.

What if my blood pressure is 160 90?

Your blood pressure is considered high (stage 1) if it reads 130/80. Stage 2 high blood pressure is 140/90 or higher. If you get a blood pressure reading of 180/110 or higher more than once, seek medical treatment right away. A reading this high is considered “hypertensive crisis.”
