Earthworms have no specialized respiratory structures and gas exchange occurs by simple diffusion through a liquid film on the surface of the body, which must be kept moist (Curtis & Barnes, 1989). The earthworm has a closed circulatory system, of which the dorsal blood vessel is the principal pumping organ (Hickman et al., 2008). The blood is transported in this vessel by peristaltic waves of contraction and carries food, wastes and respiratory gases (Hickman et al., 2008). A closed circulatory system has an advantage over open systems as it can support a faster metabolic rate (.
