Because blood is actually blue, but once it hits the air, it turns red!
Red veins carry oxygenated blood.
your veins look blue because your blood has no oxygen, when your blood is oxygenated it is red and when it is deoxygenated it is blue. veins carry blood toward the heart and are often blue while arteries carry blood away from the heart and are filled with oxygenated blood.
The difference between blue and red veins primarily relates to the oxygen content of the blood they carry. Red veins, or arteries, carry oxygen-rich blood from the heart to the body, giving them a bright red color. In contrast, blue veins are typically veins that carry oxygen-depleted blood back to the heart, which appears darker and can look blue through the skin due to the way light penetrates and reflects off the skin. However, the blood itself is never truly blue; the blue appearance is an optical illusion.
Okay well what veins of the body do is they carry blood towards the heart. basically they are blood vessels. the difference between veins and arteries is that arteries Carrie oxygenated blood and veins carry deoxygenated blood that it also why veins are greenish- blue
Veins are blue in color, they carry deoxygenerated blood which has greater absorption coefficient than the oxygenated blood that runs in artery which is mainly responsible for the blue color.
To symbolize that arteries carry blood that's rich in oxygen while veins carry blood that's low on oxygen.
Blood is not actually blue in veins. The misconception that blood is blue in veins comes from the way light interacts with our skin, making veins appear blue. In reality, blood is always red, whether it is in the veins or arteries.
NO, no, no, no, no! That is a silly question. Arteries are red, Veins are blue, Ask another question like this and ur going down. Veins are blue because they carry de-oxygenated blood and wastes, not arteries
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.
Yes. Veins transport blood to the heart, while arteries transport blood away from the heart.
Blood is blue in your veins!
A blood seems blue in veins because when a blood is in veins they are low in oxygen and therefore look blue. When they get oxygenated, they become red and are carried by the artery.
