Do Arteries carry blood under high or low?
Arteries carry blood under high pressure.
Are veins under high pressure?
No, veins are not under high pressure. High-pressure vessels are the arteries.
Why do arteries have thicker walls then veins?
Because arteries are narrower, thus increasing the pressure in the arteries. So you need thicker walls to contain the blood under pressure.
Why don't veins have be as strong as arteries?
They don't need to be as strong as the arteries because as blood is returned to the heart, it is under less pressure. Blood in arteries is under intense pressure from the heart, which is a pump.

Is arteries are always under pressure?
Yes they are. Arteries are blood vessels going away from the heart which is Why they are always under pressure. This is achieved when the heart constricts and relaxes
Does the veins or arteries depend on the respiratory and muscular pumps?
Arteries are under pressure from the heart.
Why are valves not present in arteries?
valves are not present in arteries because in arteries there is high blood pressure
How does the structure of the arteries enable them to withstand high pressure?
Arteries are able to withstand the enormous pressure of blood as it is pumped by the heart and to expand and relax between heart beats.
Are capillaries under high or low pressure?
Average pressure, think about it as the distance from the heart. Capillaries are exactly the half way point between veins and arteries. Arteries are high pressure, veins are low pressure.
Why is the blood pressure higher in the arteries?
The heart pumps the blood through the arteries, causing the arteries to be under pressure. The veins are under very little pressure as they are the vessels that collect the deoxygenated blood on it's way back to the heart. The venous blood is helped along by the movement of the muscles in the body as the body moves.
