Red blood cells have a slightly indented, flattened disk shape. In larger and more-complex animals, transport of adequate amounts of oxygen and other substances requires some type of blood circulation. In many invertebrates the respiratory pigments are carried in solution in the plasma, but in higher animals, including all vertebrates, the pigments are enclosed in cells; if the pigments were freely in solution, the pigment concentrations required would cause the blood to be so viscous as to impede circulation.
