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.
No, the blood is always red. The term,' blue blood' is given to noble people.
A barber would give people shaves!! They would also be a dentist and do blood "letting". They would open up the persons veins and take blood.
He believed that blonde blue eyed people were the perfect race , what a joke he himself was dark eyed and had black hair for that matter WHO ib the top Nazi"S was blond and blue eyed certainly not Himmler. look at any photo of him and he looks like he has asian blood in his veins.
No. Geese and ducks have one of the most effective circulatory system of any animal. The veins carrying the warm blood (to the feet) and the veins carrying the cooler blood (away from the feet) are so close together that the warm blood warms the cooler blood and prevents the animals feet from freezing. However, they must feel a little uncomfortable. Ducks and geese will sit in the water even in the coldest temperatures because the water is always warmer than the land.
Everybody's arms are different. Some people have more opaque skin, so they can't see the veins as well and vice versa. Fat will also get in the way, so you could try losing weight. I also heard that putting pressure regularly on one area for extended periods of time will cause your veins to look more prominent but that's not good for you.
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.
Blood is blue in your veins!
It's not. Blood is only darker red when it is in veins.
they enter the blue veins
Blood becomes blue when it is deprived of oxygen. These veins are returning de-oxygenated blood to the heart, making them appear blue.
No, it is not true that our blood is blue in our veins. Blood is always red, but it can appear blue when seen through the skin because of the way light interacts with our blood vessels.
Blood appears blue in veins due to the way light interacts with the skin and the blood vessels. The blue color is not actually the color of the blood itself, but rather a result of how light is absorbed and reflected by the skin and the veins.
Red veins carry oxygenated blood.
No, it is not true that your blood is blue in your veins. Blood is always red, but it can appear blue when seen through the skin because of the way light interacts with the skin and blood vessels.
That you are a human.
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.
Veins are blue because the blood is poor in oxygen, arteries are red because the blood is rich in oxygen.
