What are arteries and vains used for?

Answer 1

The artery in the circulatory system contains the oxygen enriched blood cells coming from the lungs and heart out to the rest of the body. The vain is the mental egotistical outlook of oneself. The vein is the circulatory system containing the carbon dioxide waste of the body's cell returning to the lungs and heart for the exchange to oxygen before going back to the artery.

Answer 2

They are very much different:

• arteries carry high pressure blood away from the heart, veins carry low pressure blood back to the heart
• arteries are more elastic than veins in order to handle the pulses of high pressure
• major veins (like in the legs) contain antibackflow valves (when these fail blood pools in the veins and you get varicose veins)
• etc.

Answer 3

Arteries help maintain blood pressure and carry blood away from the heart to tissues for gas exchange. Veins can act as a blood reservoir (predominantly in the legs) and carry blood back to the heart.

Answer 4

The appearance of veins and arteries are nearly identical except the size. An artery is much thicker or wider than a vein due to the musculature within the arteries.

Answer 5

The Vein is the main blood supply that is constantly carrying blood around the body.
