Blood moves away from the heart in arteries and back to the heart by the veins. Blood in the arteries is more red because it is high in oxygen. It is darker in the veins as it has lost much of it's oxygen
Blood is not blue in the veins but dark red. It looks blue because of how much light the blood is absorbing, in the color spectrum blood can absorb almost any color. It can absorb red, but it actually absorbs blue, but blue can't penetrate through the skin. At times the femoral vein (in the leg) is called "big blue".

Your blood is red. It is always red.
the three blood vessels are the Veins capillaries Arteries the arteries.
Arteries drain (pump blood) into veins. Veins drain into your lungs and heart to be re-oxygenated. (This is not true for veins and arteries to and from your lungs.)
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.
Veins do not pulsate Arteries pulsate Veins can easily collapse Arteries do not collapse (except in shock) Veins contain valves Blood pressure is low in the veins and higher in the arteries
Capillaries, arteries, and veins are the kinds of blood vessels.
Veins - veins run throughout the body, their main job is to deliver deoxygenated blood to the heart so it can get oxygenated and continue circulation. (They are usually are shown as color blue on the models of the circulatory system) Arteries - arteries are body's largest blood vessels. They main job/function is to take the oxygenated blood from the heart and deliver it to the rest of the body.(arteries branch out to capillaries and other smaller blood vessels).(they are usually shown as color red on models of the circulatory system)
arteries and veins
It is not true. Blood is also runs in arteries. Arteries take the blood throughout your body and veins take the blood back to your heart.
arteries carry oxygenated blood, veins carry deoxygenated blood. that's why arterial blood is lighter in color than blood from veins.
The veins.
blood travels away from the heart through arteries and blood travels to the heart through the veins
Arteries carry blood away from the heart. Veins return blood to the heart.
