Question 2

Describe the amphibian heart structure and the flow of blood through the heart and body.

Accepted Answer

The amphibian heart has three chambers: two atria and one ventricle. The blood flow through the heart and body starts when deoxygenated blood from the body enters the right atrium. From there, it is pumped into the ventricle and then to the lungs to become oxygenated. The oxygenated blood then returns to the left atrium and is pumped into the ventricle again. From the ventricle, the oxygenated blood is pumped out to the body. This means that oxygenated and deoxygenated blood mix in the single ventricle, which is a unique feature of amphibian hearts. This mixed blood is then circulated throughout the body, providing oxygen and nutrients to the tissues.
