Detailed explanation-1: -Fishes have only two chambers of the heart-the atrium and ventricle. The oxygenation of blood happens through the gills.
Detailed explanation-2: -The 2-chambered heart is a simple organ that pumps blood for animals with gills and single circulation. 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.
Detailed explanation-3: -Final Answer: A two-chambered heart is present in fish.
Detailed explanation-4: -The systemic heart of fishes consists of four chambers in series, the sinus venosus, atrium, ventricle, and conus or bulbus. Valves between the chambers and contraction of all chambers except the bulbus maintain a unidirectional blood flow through the heart.
Detailed explanation-5: -Abstract. The systemic heart of fishes consists of four chambers in series, the sinus venosus, atrium, ventricle, and conus or bulbus. Valves between the chambers and contraction of all chambers except the bulbus maintain a unidirectional blood flow through the heart.
