capillaries actually aren't arteries. arteries, veins, and capillaries are the major blood transport networks. arteries take blood away from the heart, veins take it back, and capillaries go between the two. capillaries are the smallest of these networks tho
arteries are 500 cells thick naa jks they are one cell thick
an average luminal diameter of 5-10 um
about how thick are the largest arteries?

arteries
Because they have to deal with high pressure blood
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.
arteries are thick walled blood vessels carring oxygenated blood from heart to the various parts of the body.pulmonary arteries act as veins and carry deoxegenated blood from the right auricle to the lungs,Thus it is different from the arteries

Arteries ALWAYS bring blood away from the heart. Vein bring it back.
because they carry blood from the heart.
arteries
arteries thick walled and elastic blood vessels capillaries and veins
Arteries carry blood with oxygen to the heart. Veins carry blood full of carbon dioxide to the lungs. Arteries have a thick wall. Veins have a thin wall. Arteries have no valves. Veins have valves.
Arteries are part of the body. They are located everywhere!! They are very thick and important.
arteries
Arteries have thick muscular walls to push your blood and spread out the pulse so it lowers its pressure. Your blood pressure is quite high when it leaves your heart and it comes in pulses. When it finishes going through your arteries and into your capillaries, your body wants it to go slow and be gentle. The muscles in your arteries change it to a smoother flow as they push it along.
All arteries have thicker wall than veins because they have to resist the pressure of the blood being pumped from the heart
