Is blood blue in ur veins or is it red?

Answer 1

The blood is always red. there are a few conditions which will cause some hemoglobin molecules to convert to methemoglobin which is blue (even though overall the blood will still be red), but that is a pathological process and is not normal. There are also some crabs that use copper instead of iron that have blue blood.
Look at it this way. go give blood. Look at the bag. the blood in there is a dark red, and it is venous blood that has not been exposed to oxygen. Oxygenated blood is a bright red, the same color as the blood you bleed, since that becomes oxygenated as well.
This myth comes from the bluish appearance of veins and of cyanotic tissue, as well as blue used on anatomical models to differentiate veins from arteries. Either way, blood is red, is always red, and is not blue.

Answer 2

What color is blood …really ?
Human blood is made up of a liquid part and a solid part.
The liquid part, when it is still in the body, is called plasma.
It is yellowish in color. It makes up about 50 - 60 % of our blood. The solid part is made up of cells; red blood cells, white blood cells and platelets. White blood cells and platelets have no color but appear white when they
are grouped together, as when blood is separated in a centrifuge. Together they make up less than 1 % of the blood. They are pictured in text books as having a variety of colors. This is because they can be stained with various dyes after they are removed from the body then placed on a glass slide.

Red blood cells are always red. Since RBCs make up about 40-45% of our blood, the blood is red. Red blood cells are red because they have a protein called hemoglobin which contains iron. Iron likes to bind oxygen. Oxygen combined with iron is red. The more oxygen iron has bound to it, the redder it is.

It is true that some persons have "iron poor blood". In this case their red blood cells are less red than normal, but they are still red. The iron in the hemoglobin of red blood cells is what carries oxygen to every tissue in the body.

Why some people may think that blood can be blue is probably because of the color of our veins, which may be visible near the skin's surface. They appear blue because they do not get as much oxygen as the other tissues.

When the red blood cells go to the lungs, the iron in them picks up oxygen. Blood then goes to the heart and then to the rest of the body through vessels called arteries. The arteries appear reddish as do many other organs, because the iron in the blood gives up its oxygen to the cells that need it as the red blood cells travel throughout the body. By the time the
blood is back on its way to the heart and then to the lungs it has less than half as much oxygen as it did before. The veins, therefore, do not get as much oxygen as the other tissues and they appear bluish.

The bottom line is: blood is red.

Answer 3

Blood is a DARK RED inside the body, almost maroonish. The many layers of your skin make your veins appear to be blue or green. When blood is exposed to oxygen, it turns a bright red. In DIAGRAMS of the heart, some cavities of the heart are colored blue to show that the blood going in that area are not enriched in oxygen.

Answer 4

Guys: Blood is red due to its iron content. Turning from blue to red upon contact with oxygen is a wive's tale. Haven't you ever watched a science program showing the interior of the body. I guarantee you haven't ever seen blue blood.

Answer 5

I did a podcast on this topic - listen to it here:

Unless you're an octopus, your blood is red.

In people who are having a cardiac arrest and have almost no oxygen in their blood, it's a very dark red, almost black. But never blue.

Answer 6

What color is blood …extremely ? Human blood is produced from a liquid area and a staggering area. The liquid area, while it remains interior the physique, is termed plasma. it extremely is yellowish in color. It makes up approximately 50 - 60 % of our blood. the solid area is produced from cells; pink blood cells, white blood cells and platelets. White blood cells and platelets have not any color yet look white while they're grouped jointly, as while blood is separated in a centrifuge. jointly they make up under a million % of the blood. they're pictured in text fabric books as having a type of colorings. this is through fact they are in a position to be stained with countless dyes while they're faraway from the physique then placed on a glass slide. pink blood cells are consistently pink. through fact RBCs make up approximately 40-40 5% of our blood, the blood is pink. pink blood cells are pink through fact they have a protein referred to as hemoglobin which includes iron. Iron loves to bind oxygen. Oxygen mixed with iron is pink. The greater oxygen iron has certain to it, the redder it extremely is. it extremely is actual that some persons have "iron undesirable blood". thus their pink blood cells are much less pink than common, yet they're nevertheless pink. The iron interior the hemoglobin of pink blood cells is what includes oxygen to each tissue interior the physique. Why some people could think of that blood could be blue is probable through colour of our veins, which could be seen close to the floor's floor. they look blue through fact they don't seem to be getting as plenty oxygen through fact the different tissues. while the pink blood cells pass to the lungs, the iron in them possibilities up oxygen. Blood then is going to the middle and then to something of the physique with the aid of vessels referred to as arteries. The arteries look reddish as do many different organs, through fact the iron interior the blood supplies up its oxygen to the cells that prefer it through fact the pink blood cells return and forth in the process the physique. via the time the blood is decrease back on its thank you to the middle and then to the lungs it has under 0.5 as plenty oxygen because it did formerly. The veins, hence, don't get as plenty oxygen through fact the different tissues and that they look bluish. the base line is: blood is pink.

Answer 7

It is different shades of blue or deep violet, depending on which part of the heart it has passed through. When it hits the oxygen, iron in your blood reacts (basically, it rusts) and turns red. I.E--Bright red blood has already been oxidized to some extent before hitting the air, whereas darker, crimson colored blood has not been.

Answer 8

the blood in ur veins is blue. but the blood in ur ateries is red. ur arteries take blood away from ur heart and blood in ur veins take blood back to ur heart. once the blood is in ur heart it takes the blue blood that doesnt have oxygen and gives it oxygen, turning it red. this red, oxygened blood goes into ur arteries and takes it to other parts of ur body. [then once it goes to ur body and drops off the oxygen it turns blue and goes in ur veins and back to ur heart. the cycle keeps on going!]

Answer 9

Red. But blood in arteries is brighter red. When you cut yourself you usually get venous blood.

Answer 10

It is red. The shade of red can tell you your level of iron in the blood, the darker the shade the higher your iron level.
