The blood flow in earthworm is a closed circulatory system. It has <span>three main vessels that supply the </span>blood<span> to organs: arotic</span><span> arches, dorsal </span><span>and ventral </span>blood vessels.
<span>Dorsal vessel is the main collecting vessel. It sends blood to anterior region where it sends blood to lateral oesophageals and to the heart.</span> Ventral vessel is the main distributing vessel. It sends blood to integument, ventrointestinal, and reproductive organs.
