Blood travels through the arteries and veins, delivering oxygen and nutrients to body cells. Blood that is carrying oxygen is bright red, but it becomes dark purple after it gives up that oxygen to body tissues and enters the veins. In general, the blood itself changes very little with aging, but diseases that cause abnormalities in the blood are common in older people.
