| It is blue in the body and red in the outside; it is red because the open oxygen haz chemicals that react with the molecules in the blood or something. |

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. |

| Blue in the body, red on the outside. This happens because in the body,the blood does not travel with oxygen, therefore making it blue. |

| If you tl;dr term's copy&paste, the more oxygen it has, the redder it is. EI: Leaving the lungs it will be red, coming back it will be blue, left out of the body to long the blood will go from purple to blue to red to brown. |

It does not turn blue Non-oxygenated blood is just a deeper color red then oxygenated blood. |

| Blue is the tissue of your vain. I mean your vain isn't blue it just makes the shade of it makes your blood appear bluish and sometimes just red. It is not blue |

What I think: Our blood inside of us is BLUE but once our blood hits OXYGEN it makes it turn RED. |

@last, I agree. But, blood carries oxygen, therefore, it's always red. When it goes back the heart, and the oxygen is used up, it's more blue in color. |

| Blood is ALWAYS red, it is just different shades of red. Think of a vacutainer ( IT is a vacuum on a glass tube) when blood is drawn from a physician such as a ICU nurse, It does NOT touch any additional oxygen or air of any type. It is still red. Veinous blood (veins) is never completely deoxygenated it is never completely without oxygen unless the person is dead for a period of time. Even with the person dead for a long period of time, it is still red when you remove organs or draw blood from a dead person. It is just not as red. It is a lighter shade of red therefor the vein (which is mainly clear but has a tint of blue) and the skin can make it appear blue. |

| According to my AP bio teacher they did an experiment because they had to prove that blood was ALWAYS red in the human body... and yes it is always red your veins are blueish purplish color thats where the rumor came from... now many marine animals have blue blood due to there different blood composition =3 |

| And oxygen causes no color change in your blood on that much of a scale... itd be a large waste of energy and our body would remove that waste of energy over periods of time. |
