it would have to pump blood
The amphibian's heart does pump out a mixture of oxygen-rich and oxygen-poor blood. They are vertebrates, and this is how vertebrates' circulatory systems work.
A pig's heart is very similar to the human heart in that it has 4 chambers while an amphibian heart has only 3 chambers. The pulmonary system in an amphibian is low pressure and has only an atrium.
Beat.
an amphibian heart has two atria but only a single ventricle
Yes, an amphibian does have a heart.
one of which is that they both have heart arteries
An amphibian heart pumps oxygen-rich blood from the lungs (in the case of frogs and some salamanders) or through its skin (in the case of certain salamanders and caecilians) to the rest of the body. This oxygen-rich blood is then distributed to tissues and organs to support their metabolic needs.
No. Pigeons are birds.
2 atria and 1 vertricle
Yes. An adult amphibian has a three-chambered heart.
A frog is an amphibian. An amphibian heart is characterized by three chambers. Two auricles and one ventricle constitute an amphibian heart. Hence, an amphibian heart appears like a pyramidal structure turned upside down.
they have diff. no. of chambered heart
