Ok so today my brother asked me what color is blood so I said red and he said I was wrong its actually blue. I asked him who told you that and he said his teacher, he said that his teacher told him your blood is blue when it is inside the body and when it comes out it touches oxygen it turns red. I was like wtf and I was thinking isn’t the blood’s job is to carry blood around the body so it is touching oxygen so if it would be red even in the body. am I right I mean it makes sense right. ---

read this > **[Blue Blood/Red Blood](http://www.globalclassroom.org/blublud.html)** > > A discussion of blood and the circulatory system with the kids at Delmar Elementary School, Delmar, MD > Blood is _never_ blue. Blood is described as dark red (venous) or bright red (arterial). ---

blue blood? rofl… light does not penetrate your skin and to your veins, therefore not absorbing blue, and that’s why your veins look BLUE blood is actually darkish red / black, there is a small chemical reaction that occurs when your blood (with particles of Iron (Fe)) react with particles of Nitrogen and Carbon Dioxide in the air ---

haemoglobin helps to colour it cause it is a red pigment, and that carries the oxygen around the body 😛 ---

oh god, there are arteries and veins in our bodies. veins take “non-pure” blood back to the heart, so the “non-pure” blood is blue or greenish (don’t know the exact color). arteries go out from the heart to the parts of our bodies, and this is “pure” blood, but not 100%, so they are red. ---

haha lmao! surprised u didnt know it, well technically blood is red because it contains hemoglobin which carries oxygen to the body parts, but when blood delivers oxygen to cells and exchanges it for carbon dioxide, the redness turns into a bluish shade, thats all, its not totally blue! ---

When Hemoglouin (Hb means Iron) carried Oxygen, its converted to Ferric Oxide (Fe0[SIZE=“1”]2[/SIZE]), that is when Iron is converted to rust which is red in colour. ---

> [@vini](#): > > When Hemoglouin (Hb means Iron) carried Oxygen, its converted to Ferric Oxide (Fe0[SIZE=“1”]2[/SIZE]), that is when Iron is converted to rust which is red in colour. Fe means iron. When Iron (ferric is iron with another oxidation number) combines with oxygen, it makes Ferric Oxide, or rust 😃 just clarifying. ---
