no- they have a 2 chamber heart
The term "chamber" is absolutely applicable to science. Portions of animal hearts are divided into so called "chambers." The human heart is comprised of four chambers. The heart of a fish is made up of three chambers.
Amphibians have a three chambered heart.
Reptiles and amphibians are the vertebrates that have three-chamber hearts.
The heart of a lamprey looks similar to that of modern fish in a sense. It is a two chambered heart with a single atrium and a single ventricle. The atrium of the heart is proceeded by a sinus venosus, which isn't considered an actual chamber but rather pre-heart chamber. Then after the ventricle we have a conus arteriosus that again isn't considered to be a chamber of the heart but rather a post-heart chamber. The blood flow through the heart is a one way path like that of modern day fishes.
fishes - 2 chambered heart with sinus venosus and conus arteriosishuman - 4 chambered heart
Amphibians have three chambers in the heart: Two atria and one ventricle
Squid also have 3 hearts.
Any class of vertebrate with a three-chambered heart has two atria and one ventricle. An example would be amphibians such as frogs.
The first type of heart is the simple two chambered heart, which is found in fish. The second is the third chamber heart, which is found in amphibians and reptiles. Mammals and birds have four chambered hearts.
The frog heart has three chambers: two atria and a single ventricle.
Fish are the animal group that have two-chambered hearts. Reptiles and amphibians have three-chambered hearts and mammals have four-chambered hearts.
