Protective, bony cover on gills in most fish. 2 chambered hearts of fish have single circulation and the basic design is very different from a 3 chambered heart. Fish have two chambered heart and oxygenation of blood takes place in the gills and passes directly to the rest of the body. (a) fish have the simplest circulatory systems of the vertebrates: This 2 chambered heart is present in fish.there is 1 auricle and 1 ventricle operating along with the gills. A loop from the heart goes to the pulmonary capillary beds, where gas exchange occurs.
What is ventricular in heart?
