Why is blood red?
Answer:
it is red if the iron contained by hemoglobin is oxidized or carrying oxygen. After the hemoglobin gives up the oxygen contained by exchange for carbon dioxide, then it loses its red color and appears to be shadows red. The blood coming from the lungs and heart is red because the blood is oxygenated. After giving up the oxygen in the capillary, the blood returns via the veins and as a result the blood in the vein appear dark red. It is merely blue on color charts.
Its Red Cause "GOD" Wanted It To Be
blood is NOT blue.
Oxygenated blood is red for the same apology that rusty metal is a reddish color; its the oxidated state of the iron contained by the hemoglobin in red blood cell. Blood bound to oxygen is red, while oxygen deficient blood is blue again because of the oxidation state of the iron atoms. Thats why your vein are blue, because the blood has lost much of its oxygen to your tissues.
Yes, Blood turns blue when it's deoxygenated but when it's exposed next to oxygen, it turns red.
Oh, boy! It is red inside the body; I know, I've seen contained by there. There is the expression, "Blue Bloods", referring to the aristocracy or the "rich and famous" within the States. If you look at your veins surrounded by your arms and legs, they are "blue".
Blood is red because hemoglobin contains iron, which "rusts" when it combines with oxygen, making it red. Once it loses its oxygen to the cell in the body and take on all the wilderness from the cells, it turns "blue". If you want, you could vote that blood is "clear" and the oxygen or wastes fashion it "red" or "blue".
And, yes, bones and muscles ARE white; I've seen them too.
Blood is vitally because of the complex haemoglobin. Haemoglobin is found in the red blood cell and when it is attatched to Oxygen it is red but when oxygen from the haemoglobin is released from the blood to the body tissue (where it is used to make energy) the haemoglobin change chemical shape and appears blue. When you bleed the deoxygenated blood immediately turns red because the upper air supplies it with it near oxygen. Veins which return to your heart are full of deoxygenated blood and hence veins similar to the ones on ur hands look blue (especialy if your pale)
Blood is red because the iron on the hemoglobin make it appear reddish. Think of something explicitly rusting, it has that glowing color.
In humans and other hemoglobin-using creatures, oxygenated blood is bright red. This is due to oxygenated iron in the red blood cell. Deoxygenated blood is a darker shade of red, which can be see during blood donation and when venous blood samples are taken. However, due to an optical effect cause by the way within which light penetrates through the skin, vein typically appear blue in colour. This have led to a adjectives misconception that venous blood is blue before it is exposed to nouns. Another reason for this misconception is that medical charts other show venous blood as blue in lay down to distinguish it from arterial blood which is depicted as red on the same chart.
press already answered but I'd like to specify that "blue" blood is not that blue but dark (and found in veins). More importantly it is not deoxygenated (as contained by no O2 left): just look at the dissociation curve for O2 and hemoglobin.
blood is red because of the hemoglobin containing iron surrounded by the red blood cells. It is bright red when it is oxygenated surrounded by the lungs. In the veins on the instrument back to the lungs it is ominous red. Blood is not blue. Have you ever cut yourself?
Go donate blood. That is venous blood and does not get exposed to oxygen. Go and see what color is contained by the bag, it will be dismal red. Refer to Swiss princess for a reason why it is NOT BLUE!!
Blood is a bluish color. We lone see it as red because we only see it outside the body, within the presence of oxygen. the oxygen turns the blood red.
Blood is always red. It is any bright red when it is oxygenated by the lungs or it is a dull red after it has given up it's oxygen to the cell in the body. The blue is merely the color of the blood vessel. Blood is red because when iron binds to hemoglobin it absorb all frequencies of muted except red. The red gets reflect back sour of the molecule and your eye sees the red.
