Question

What is the function of the 3-chambered heart of an amphibian?

Answer 1

Heart of an Amphibian and its function:

1. The heart is a muscular organ that is responsible for pumping blood throughout the body.
2. In amphibians, the heart is of three chambers that is two atria and a single ventricle.
3. Like humans, these animals also have separate blood circuits for transferring oxygenated and deoxygenated blood.
4. Deoxygenated blood collects the oxygen-deficient blood from the body and opens into the right atrium.
5. Lungs are the air exchange site where carbon dioxide is exchanged with oxygen, and the blood empties itself into the left atrium.
6. The blood is then pushed out of the body after entering the ventricle a second time.
7. As blood is pushed to the tissues, the second trip through the heart keeps blood pressure high and blood flows quickly, allowing the blood to carry oxygen more efficiently.
