2 question more or less blood.Not gross question.?
In camp this female said that your blood is blue and when it touches air it turns red.
But other citizens say that blood is red.
What is the REAL word?
And what colour are your cell?
Answers:
The first of your questions (is blood ever blue) is amazingly adjectives. The short answer is NO. Blood is always a shade of red (bright red when it is oxygenated, and a dark maroon when it's deoxygenated).
Veins distinctly do LOOK blue though. The reason for this is that as wispy heads towards the vein, the blue wavelengths are scattered put money on to you eye, whereas the redder wavelengths are mostly absorbed by the blood. So, since solely blueish wavelengths reach your eye, the vein look blue.

As for the colour of cells... that depends on the type of cell. Red blood cell really are a little red, for instance, or if the cell contains a great deal of lipid, it'll tend to be yellowish. Most are a sort of beige, off-white colour though, if you really want a rough answer!
Blood really is red, it of late looks blue through the vein walls.
Uh... I expect your VEINS are blue... and your blood cells are pinkish/red
Blood is red surrounded by its true colour. Blood is in a plasma gooey that contains water and blood clots. Water have samples of oxygen surrounded by it, so this means blood would other be making contact with "air". Blood may appear blue if you look at your vein.
