Why is blood red but veins are blue? also why is art important

Answers

Answer 1

Answer:

Well, i think blood is red because of the blood cells in it, and the light. And our veins hold our blood of course, and our skin is lied on top of our veins so personally i think that's why. And in my opinion, art is important because it shows emotion, and can tell a story.

Hope this helps you!

Answer 2

Answer:

because  light has to penetrate  the skin to illuminate them, blue and red light  being of different wavelength  penetrate with different degree of success .the oxygen rich blood is then pumped out to  your body through your  arteries .its  bright red at this point.
