Question

tell me??!?!?!?!

Answer 1

Isn't grass really orange, just when you look at it it turns green?

Answer 2

To check that the above answers are correct (that veinous blood is bluish-red, and not blue), try this simple test:

Notice that the vein in your wrist appears to be bluish. Then place a blue pencil alongside the vein. You will then notice that the vein now appears red, compared to the pencil. It seems blue , compared to the surrounding flesh. Also, you are looking at the vein itself, rather than the blood within it. I often give blood samples for tests, and the blood from my veins is brick red.

Answer 3

Blood with a lack of oxn. is blue any contact with the air and it turns back red.

Answer 4

Blood is always red. The color is provided by the (you guessed it - the red blood cells). However, oxygenated blood is a brighter red than non-oxygenated blood. Non-oxygenated blood is still red - but it's closer to burgundy.

Veins only look that color - not because of the blood in them.

Answer 5

Arterial blood is very red because it's freshly oxygenated. Venous blood (blood in your veins) is bluer in appearance because the hemoglobin hasn't picked up fresh oxygen to replace the carbon dioxide that it's carrying away from the tissues.

Answer 6

its red and redish-blue when the blood comes back to your heart from your veins it is deprived of oxygen and its appearence is blue but when it is being sent out from you heart it has plenty of oxygen making it red
