Large blood vessels that carry blood away from the heart.

From the arteries blood flows into tiny vessels called capillaries. In the capillaries, substances are exchanged between the blood and body cells

From the capillaries, blood flows into the veins. Veins are vessels that carry blood back to the heart

From the left ventricle the blood is pumped into the aorta, the largest artery in the body.

When the ventricle muscles contract, they exert a force on the that is inside them.

The force exerted by blood on the inside walls of a blood vessel is called blood pressure. It is written in two numbers. The first number is called the systolic (contracted). The second number is called the diastolic (relaxed).
