oxygen is the answer
Arteries carry red blood cells (along with other cells) away from the heart. These red blood cells contain hemoglobin which helps to transfer the oxygen itself.
The pulmonary artery runs from the heart to the lungs. It is the only artery that doesn't carry oxygenated blood. That makes it a darker red than the blood in other arteries, so it looks blue under your skin.
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.
The pulmonary arteries carry deoxygenated blood from the right ventricle of the heart to the lungs, where the hemoglobin molecules in the red blood cells pick up oxygen molecules. The blood is being carried away from the heart, which classifies these vessels as arteries even though the blood does not contain oxygen.
arteries carry oxygen This is a trick question ! The answer above is absolutely right in that the arteries transport oxygen to everywhere in the body that might need it. The trick lies in the detail; the oxygen is not transported in the form of a gas. What happens is this. Red blood cells contain a substance called haemoglobin; it's a solid. In the lungs oxygen reacts with this to form oxyhaemoglobin (also a solid). This travels round the arterial system; when a cell needs oxygen it grabs an oxygen atom from a passing red blood cell, at which point haemoglobin reappears in the red cell. The teacher who set this question should be ashamed.
Iron.
The molecule that carries oxygen is the hemoglobin molecule. The cell that carries oxygen is the red blood cell.Blood. Red Blood cells. Or Haemoglobin in the red blood cells depending on what level you are looking at.The protein that carries oxygen in the blood is Haemoglobin(hemoglobin).
oxygen makes your blood red. The Lungs put lungs into your blood system.

the red blood cells
Red Blood Cell
The red blood cells carry the oxygen in blood.
hemoglobin is just a pigment in your blood that makes it red...carries oxygen throughout the body...
The metal element that carries oxygen in the blood is iron, which is incorporated in the hemoglobin molecule.
The hemoglobin which exists inside our RBCs (Red Blood Cells) carries the oxygen from lungs throughout our entire body.
Blood carries red blood cells which carries blood around your body
There is a protein in red blood cells called hemoglobin. This is the substance that carries oxygen throughout the bloodstream.
