Question

what is the advantage if a four chambered heart

Answer 1

Dude your answer is here 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.

Answer 2

Answer:The right and left parts are separated by a septum to prevent oxygenated and

deoxygenated blood from mixing. This fulfills the constant use of energy to maintain their

body temperature. Their energy needs are high, which are fulfilled efficiently because of non

– mixing of oxygenated & deoxygenated blood.
