The blood vessels carry blood, which contains antibodies, nutrients, oxygen, electrolytes and hormones, throughout the body to be used by the organs.eins. 1  Veins carry blood from throughout the body back to the heart. 2  The blood in the veins is dark red in color because it contains very little oxygen. 3  The walls of veins are not as strong as the walls of the arteries because they farther away from the heart, meaning they are subject to less pressure from the heart.
