Question

What is the advantage of having a four-chambered heart?

Answer 1

Heart:

1. The fist-sized organ, which pumps blood all through the body is known as the heart.
2. It is the main organ of the circulatory system.
3. The four-chambered heart is commonly found in all mammals and birds, however, with the exception, it is also found in crocodiles.
4. In reptiles, the three-chambered heart is present.

Advantages of four-chambered heart:

1. It makes sure complete segregation of deoxygenated and oxygenated blood within the heart.
2. It permits a highly effective supply of oxygenated blood to all the body parts.
3. In the four-chambered heart, clear cut division of the ventricles (pumping the blood) and atria (receiving the blood) is found.
4. In the four-chambered heart, the right part of the heart is separated from the left part, which inhibits the intermixing of deoxygenated and oxygenated blood.
