What is the advantage of a four chambered heart?

Hey there,
STRUCTURE-A 4 chambered has 2 upper chambers called auricles and 2 lower chambers called ventricles. The walls of the auricles are are thinner than those of the ventricles as they have to force blood into the lower ventricles. Walls of 4 chambers are made up of myocardium. The central division between left and right is called septum.
=====================================================
FUNCTION-The right auricle receives deoxygenated blood from all parts of body via vena cava and coronary sinus.
The left auricle receives blood rich in oxygen from the lungs via pulmonary veins. When auricles contract, blood passes on to the two ventricles. This is called auricular systole.
As the auricles relax, ventricles contract, known as ventricular systole. Oxygenated blood is forced into all part of the body via aorta and the deoxygenated blood enters the lungs via pulmonary artery.
==================================================
The mechanism of 4 chambered heart in mammals and other higher animals allow easy production of energy since these animals spend a lot amount of energy in maintaining body temperature.

Heya !!!
Here's the answer
The 4 chambered hearts of higher animals has 2 auricles and 2 ventricles.
The upper 2 are auricles and the lower to are ventricles.
⏩The deoxygenated blood from all over the body is sent to the right auricle through vein.
The blood the moves to the right ventricle, from where the deoxygenated blood goes to the lungs through pulmonary artery.
⏩The oxygenated blood from the lungs enters the left auricle through pulmonary vein. Which then is poured to the left ventricle, which finally is transported to rest parts of the body.
Why do we need this 4 chambered heart?
⏩ Well this 4 chambered heart is a very efficient way of transportation.
⏩This does not allow the deoxygenated blood to mix with the oxygenated blood.
⏩ The right part contains deoxygenated blood only and the left part contains oxygenated blood only.
⏩ This pure form of oxygenated blood also helps in proper breakdown of absorbed food to from energy.
