Don't spam ❌❌❌​

Answer 1

Human blood is red because of the protein hemoglobin, which contains a red-colored compound called heme that's crucial for carrying oxygen through your bloodstream. Heme contains an iron atom which binds to oxygen; it's this molecule that transports oxygen from your lungs to other parts of the body.

Answer 2

Answer:

Explanation:

Human blood contains hemoglobin, which is a complex protein molecule in red blood cells. Hemoglobin contains iron. The iron reacts with oxygen, giving blood its red color.Maybe you've heard that blood is blue in our veins because when headed back to the lungs, it lacks oxygen. But this is wrong; human blood is never blue. The bluish color of veins is only an optical illusion. Blue light does not penetrate as far into tissue as red light.01-Jun-2018
