Question

what is the benefit of human heart having four chambers.

Answer 1

hey mate here is the answer....

The four-chambered heart has a distinct advantage over simpler structures:
It allows us to send our "dirty" blood to the cleaners-the lungs-and our "clean" blood to the rest of the body without having to mix the two.
That system is very efficient.

thanks...
nice to help you

Answer 2

GOOD AFTERNOON

Presence of four chambered heart serves two purposes. First, it ensures complete segregation of oxygenated and deoxygenated blood. Second, blood is received by the upper chambers and is pumped out by the lower chambers. This segregation between received blood and sent blood increases the efficiency of the heart.
