What is the advantage of having four-chambered heart?

AcademicBiologyNCERTClass 10

The Four-chambered heart has the following advantages:
(a) There is a clear-cut division of labor among different chambers. Atria receive blood and ventricles pump the blood to the rest of the organs of the body.
(b) There is complete segregation of oxygenated and deoxygenated blood in the heart by a septum.
(c) A four-chambered heart is highly efficient.
