Are your arteries blue because of they carry blood with wastes?
arteries are blue because they carry blood away (a for away) from the heart, so the blood is highly oxygenated. When the blood goes around the body is becomes redder in colour as it is losing its oxygen to various muscels via capillaries. So no, the blood in arteries is not blue because it carries waste, it is blue because of the high oxygen levels in it. Blood can carry some waste though which gets taken i think to the kidneys.
