Blood vessels contract slightly to help the flow of blood
As the heart beats, it pumps blood through a system of blood vessels, called the circulatory system. The vessels are elastic tubes that carry blood to every part of the body.

Veins have valves to make sure that blood flows in only one direction.

Blood flow is faster in arteries than in veins. Blood flow in veins is lower pressure.
How part of the theory of circulation was changed?
People used to think that blood could flow in any direction in the veins. William Harvey came up with evidence used to show that blood moved only in one direction through veins. He discovered that the valves in the veins permit blood to flow in one direction only. He said that blood circulates in only one direction through the body and returns to the heart.
Why are valves present in veins but now in arteries?
valves are only present in veins to stop the blood to move backwards through the vein but in arteries the muscle puts alot of pressure on the blood which stops it from moving in the wrong direction
How are heart valves similar to valves in veins?
in both the valves blood flow in one direction.
Why does blood flow in the direction it does?
the blood does not flow in the wrong direction because it flows in veins.
