The Circulatory System. Veins, arteries and capillaries are the three types of blood vessels in the circulatory system. The blood vessels carry blood, which contains antibodies, nutrients, oxygen, electrolytes and hormones, throughout the body to be used by the organs.lood contains oxygen and nutrients the body needs to survive. The arteries, veins and capillaries are types of blood vessels that transport the vital blood throughout the body. Learn the differences between the types of blood vessels.
The walls of veins have the same three layers as the arteries. Although all the layers are present, there is less smooth muscle and connective tissue. This makes the walls of veins thinner than those of arteries, which is related to the fact that blood in the veins has less pressure than in the arteries.Because the walls of the veins are thinner and less rigid than arteries, veins can hold more blood.apillaries. Capillaries, the smallest and most numerous of the blood vessels, form the connection between the vessels that carry blood away from the heart (arteries) and the vessels that return blood to the heart (veins).
