Because blood leaves the gills and immediately circulates to the rest of the body, the heart does not require additional chambers beyond the first two. Fish and other animals with 2-chambered hearts, therefore, have simpler circulatory systems than animals with lungs and subsequently, 3- and 4-chambered hearts.
