Cancer refers to abnormal cells, which have a tendency to grow uncontrollably and metastasize or spread to other areas of the body. Like bryozoans and phoronids, brachiopods have a lophophore, a crown of tentacles whose cilia (fine hairs) create a water current that enables them to filter food particles out of the water. Like other arthropods, spiders are coelomates in which the coelom is reduced to small areas around the reproductive and excretory systems. Each filters out water and solutes from the blood which passes through it into the surrounding space and is the cavity which is between the walls of the cup.The other part looks like the form of a U-shaped loop carrying the filtered fluid deep down into the medulla.
