Answer: Multicellular animals do not have most of their cells in contact with the external environment and so have developed circulatory systems to transport nutrients, oxygen, carbon dioxide and metabolic wastes. Components of the circulatory system include

blood: connective tissue of liquid plasma and cells

heart: a muscular pump to move the blood

blood vessels: arteries, capillaries and veins that deliver blood to all tissues
