No, they usually carry low oxygen blood except for the pumonary veins which carry oxygen from the lungs to the heart.

Do arteries contain more oxygen or carbon dioxide than veins?
Arteries carry blood away from the heart and veins carry blood into the heart. Blood moving from the heart to the lungs through the pulmonary artery has less oxygen than blood moving from the lungs to the heart through the pulmonary vein, but most arteries carry oxygen-rich blood with little carbon dioxide, and most veins carry deoxygenated blood with carbon dioxide and other wastes.
Why is the strcture of arteries different from veins?
This is because arteries have more force going through them than veins do. Arteries have a higher level of pressure as opposed to veins who are more relaxed and just have blood being pushed along through them rather than FORCED. If you put a vein in place of an artery, it would probably just burst.
What carry the purplish or blue blood back to the heart to get more oxygen?
Veins carry the blood back to the heart and lungs for more oxygen. then the arteries carry the blood that now has oxygen it it to the rest of the body.
What contains more oxygen veins or arteries and why?
arteries is the oxygenated
How does the direction blood travels in arteries and veins differ?
the blood in the arteries in oxygenated and is flowing away from the heart throughout the body tyo give your cells oxygen. the blood in the veins has had its oxygen depleted by your cells and is travelling back to the heart and lungs to get more oxygen
Do arteries transport carbon dioxide in the cells?
Arteries don't always carry blood that is high in oxygen. The term artery is an anatomical term. All blood vessels that carry blood away from the heart are arteries. All blood vessels that carry blood back to the heart are veins. Most arteries do carry blood that's high in oxygen but there is an exception. When the arteries carry blood to the lungs, this blood is low in oxygen. The veins that carry the blood back to the heart from the lungs is high in oxygen. This is called the pulmonary circuit. In this more or less seems backwards. It's best to remember that arteries carry blood away from the heart.
Why are veins darker in colour than arteries?
Veins are not actually darker than arteries. In fact, on dissection, veins and arteries are both a whitish color. The reason that they are more visible is because there are larger veins that are located closer to the surface of the skin than arteries. Veins also tend to have thinner walls, making the blood inside them more visible.
Do arteries carry blood to the heart and veins carry blood from the heart?
No. Arteries carry blood from the heart to the rest of the organs, and veins carry blood back to the heart. All arteries have high pressure from being pumped by the heart so recently, and all veins have low pressure from travelling round the body for so long. Most arteries carry oxygenated blood (except for the pulmonary artery, which goes to the lungs to pick up more oxygen) and most veins carry deoxygenated blood (except for the pulmonary vein, which has lots of oxygen from the lungs).
Do arteries feed the veins?
Hmm; in a sense, yes. A more complete understanding would have arteries feeding capillaries, which feed the muscle or organ fresh blood, which is returned to the circulatory system by veins. Arteries carry oxygenated blood; veins return the now oxygen-depleted blood to the lungs, then heart, and back to the arteries, in brief.
What differences did you observe in the structure of an artery and vein of the umbilical cord?
Arteries have a smaller lumen (centre passage) than veins do, they also have thicker more 'muscular' walls than veins do. This is because blood pressure is higher in arteries than in veins, as arteries carry blood away from the heart, veins carry blood to the heart, pressure has to be high in arteries so that blood can reach all around the body.
Does veins or arteries have oxygen?
More, not less. Oxygen is moved into the arteries by the lungs and pumpled by the heart through the body. As the cells use the arterial oxygen they create carbon dioxide as a byproduct of metabolism. This waste is sent to the veins where the heart pumps it back to the lungs to be exhaled with the breath.
What is the arteries main function?
Most arteries carry oxygenated (oxygen-rich) blood from the heart to the rest of the body. Most veins carry deoxygenated (containing less oxygen and more carbon dioxide and other wastes) blood from the body tissues to the heart, which then sends that blood through the pulmonary system to be oxygenated again. The only exception to this is the pulmonary system. The pulmonary veins carry oxygen-rich blood back to the heart and the pulmonary arteries carry deoxygenated blood from the heart to the lungs.
