No. But the 'used' blood on its way back to the lungs is dull red, and looks blue through the veins.
No, human blood is never blue.
No, human blood is red.
Yes. It is true.
That's easy. When blood is in your body it is blue that's why your veins are blue. When oxygen meets the blood the blood turns red.
As far as I know, it is the blood of your body that carries oxygen to all of your body parts.
The colour of all whales' blood is red, not blue.
In relation to the human body, it is a common misconception that blood is blue; all blood is red. The blue appearance is due to the connective tissues of the blood vessels. Blood cells can be either erythrocytes, which are red, or leukocytes, which are white. When blood is oxygenated it is a much brighter red than de-oxygenated blood.
In the human body, the color of blood is a blue. But when you get a cut or something like that, the blood immediately turns to red the second it gets mixed with air.
No, they carry blood rich with oxygen away from the heart to all the body.
Humans have a few different blood types. However, a spider is an arachnid, and it does not have a blood type.
This is a false statement. While most of the arteries in the body carry oxygenated blood, the Pulmonary Arteries carry de-oxygenated blood from the Right Ventricle of the heart to the lungs.
Your blood is bright red in the artery and dark red in veins. You do not have [ blue blood ] . It only appears blue because the veins which are white are are carrying dark red blood and being viewed through the skin which difuses the light and makes them appear blue. that is partly true but I have herd from all my teachers that your blood is blue in the arteries. Which when you get cut the air puts oxygen in the blood stream that makes the blood turn red. answer #2 The statement that blood is blue inside the body and turns red when in contact with blood makes little sense. How can this be so when blood itself is used to transport oxygen throughout the body? It is not possible for blood to be blue inside the body as well as carry out one of it's main functions. Answer#3 Actually blood is red in the arteries and blue in the vein. Blood in the artery has already combined with oxygen whereas blood in the vein has yet to receive oxygen. So in fact there is both red and blue blood. When a vein is cut open it hits oxygen in the air causing it to turn red. Answer#4 The protein hemoglobin, which carries oxygen in the blood, changes shape when it binds oxygen. When it changes shape, it absorbs different wavelengths of light, making it change color. When blood is exposed to air, much more of the hemoglobin absorbs oxygen than had in the vein the blood came from (in the veins, the hemoglobin has already given up most of its oxygen to the body). Therefore, the blood turns red. This also means that blood in the body, once it has been oxygenated, is also red, though much more so when it reaches open air. I think it would be a fun experiment to put your hand in a vacuum chamber with a tight seal around your wrist and prick your finger to see the difference in blood color.
duhhh the nervous system
The blood in our heart is carried to all parts of our body. The heart pumps the blood, and the blood is carried by veins. The veins are all over our body. They have a system; out to our body, and back to the heart.
