When bleeding why does your blood have two distinct colorations?

Blood can be a bright red color or a dark red color. The reason it is two different colors is because of the oxygen it contains. Blood in the arteries is bright because it is oxygen-rich, but the blood in the veins contains wastes like carbon dioxide instead so it is a darker color. My anatomy teacher emphasizes that blood is not blue (except in some animals like crabs for example) and it only looks blue through our skin. :)


What is hemocyanin?

What are different colors of blood in animals?

Blood color in animals varies primarily due to the type of respiratory pigment present. Most vertebrates, including humans, have red blood due to hemoglobin, which contains iron. Insects and some crustaceans have blue blood because their hemolymph contains hemocyanin, which uses copper for oxygen transport. Other variations include green blood in some worms and leeches due to chlorocruorin, and purple blood in certain species of octopus, which also rely on hemocyanin.


What color blood cell brings oxygen to cells and takes carbon away?

The red blood cells carry oxygen to the tissues, absorb CO2, then carry it away to the lungs to get rid of it. Haemoglobin is the name of this magic chemical. Some animals use a copper-based equivalent which is blue!
