What is the difference arteries veins and capillaries?

Arteries- carry blood away from the heart. (I like to think Arteries Away.)Veins- carry blood to the heart.Capillaries- connect veins and arteries.Arteries are the tubes or vessles which carry the blood away from the heart once the blood has been oxygenated by the lungs. When it leaves the heart, it will begin the systematic circut, where the arteries get smaller and smaller, and become capillaries. Capillaries are smaller extensions of arteries and veins, supplying blood tho the bodies extremities. When the arteries deposit the oxygen and other nutrients through the capillaries, the blood then moves to the veins, which will carry the blood back to the heart. The veins are made from all the capillary branches moving back to gether. Veins have lower pressure than arteries, and also carry the deoxygenated "blue" or dark red blood, which will turn back to bright red once the blood is replenished in the heart, where the process starts again. So, * Arteries are the thick tubes carrying oxygenated blood from the heart to the extremities and organs, * Capillaries are the fine branches of arteries or veins which supply blood to the bodies extremities, * and veins are the thinner tubes carrying the deoxygenated blood back to the heart In other words:Arteries: carry rich blood from the heartVeins: carry poor blood to the heart
