How are veins and artery different?
The walls of arteries are composed of muscle which allows the artery to widen or narrow so as to control blood pressure within. Veins have little one way valves in them to keep blood moving in one direction only. Blood in veins is under not much pressure wheras blood in arteries is under much more pressure as this blood has just been pumped by the heart.
What happens to blood pressure as blood moves from arteries to veins?
Blood pressure decreases as blood moves from arteries to veins. For this reason, veins have valves to encourage the one-way flow of blood back to the heart.
If blood pressure is low in veins how does blood getpumped through the veins back to the heart?
Veins have valves in them which help transport the blood.
Is blood flow faster in veins?
Blood flow is faster in arteries than in veins. Blood flow in veins is lower pressure.
Do veins have thin walls?
Relative to the walls of arteries, the veins' walls are thinner, because the pressure of the blood in the veins is much lower; so low in fact, that valves are required to prevent blood in the veins flowing backwards.
What blood vessels have lower blood pressure?
veins.
The vessel with valves that keep blood from flowing in the right direction?
Veins have valves to make sure that blood flows in only one direction.
Why do veins dilate?
Veins contract and expand in response to blood pressure.
Does high blood pressure affect the veins?
Veins don't carry blood at high pressure arteries carry blood at high pressure. Arteries have a thick, elastic muscle layer that can handle high pressure of the blood flowing through them.
Does pressure drop when blood moves from arteries to veins?
Yes. Blood always flows from a higher pressure to a lower pressure, so as the blood moves from the arteries through the capillaries and into the veins pressure drops considerably.
What is symptoms of blood pressure?
Throbing veins
The greatest drop in blood pressure occurs in the?
the veins
