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 to 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.
How have arteries adapted to carry blood away from the heart?
The heart pumps the blood out in high pressure so the artery walls are strong and elastic,the walls are thick and contains thick layers of muscle to make them strong , and elastic fibres to allow them to stretch and spring back
Why is it possible for diffusion to take place at the capillaries and not in the arteries and veins?
liquid can leak in and out of capillaries, and arteries and veins have such thick walls, and their jobs are just to bring blood to and from the heart. NO need for diffusion in these.
Why are the larger arteries white?
Because the the outer walls of the bigger arteries are thicker. the thinner the wall the more transparent it is. Because the the outer walls of the bigger arteries are thicker. the thinner the wall the more transparent it is.

Where does the apostrophe go in 'the arteries walls'?
The arteries' walls.
Are the walls in arteries thicker than the walls in veins?
The arterial walls are thicker because they need to withstand the pressure coming from the heart.
Why don't veins have to 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.

What has thinner walls arteries or veins?
Arteries have thicker wall because the pressure in the arteries is much higher.
Do arteries have thick walls compared to other blood vessels?
Yes, arteries have thicker walls compared to other blood vessels.
Why are some blood vessels more muscular than others?
The blood vessels that carry blood away from the heart, arteries, need to withstand the pressure exerted by the heart as it pumps to the blood to the lungs and to all the tissues of the body. These have thicker muscular walls, veins deal with far less pressure, so their muscular layer is thinner.
Why do arteries have thick walls?
Arteries have thick walls to withstand the high pressure of blood flow from the heart to the rest of the body. The thick walls help maintain the shape and structure of the arteries, allowing them to efficiently transport oxygen and nutrients to tissues and organs.
What arteriomalacia means?
Is the abnormal softening of the walls of an artery or arteries
How have arteries adapted to carry blood away from the heart?
