Compared with land vertebrates, fishes have a special problem in maintaining their internal environment at a constant concentration of water and dissolved . They have vessels that carry blood throughout the body. When the concentration of solutes, or dissolved substances such as ions, in surrounding water differs from that of bodily fluids, water enters or exits the body. Closed Circulatory system All vertebrates have a closed Circulatory system that is made of three main types of blood vessels: Arteries, capillaries, and Veins. Arteries are the blood vessels that carry blood with oxygen away from the heart and to the muscles. Flow of a single circuit system.
