why is there a complete seperation of blood in human heart
Answers
Explanation:
Separation of oxygenated and deoxygenated blood in the heart of three types of animals.
The three-chambered frog heart mixes oxygenated and deoxygenated blood in the ventricle. Therefore, the body never receives fully oxygen-rich blood. In turtles, where a septum begins to form and separate the ventricles, the body receives slightly richer blood in oxygen. It is only in the warm-blooded model, in birds and mammals, that the two circulatory systems become fully separate sending low-pressure pumping to the lungs, and a high-pressure flow of blood to the rest of the body. In this model, the animal's muscles receive fully oxygenated blood.

Explanation:
the heart is divided into 4 chambers and recieves deoxygenated and oxygenated blood respectively...the septum runs down the middle seprating in two halves and the right artium and right ventricle are seperated with valves...... the right side of the heart "The right atrium" receives deoxygenated blood from systemic veins; the left atrium receives oxygenated blood from the pulmonary veins.
the deoxygenated blood for sure must not be mixed with the oxygenated blood and for this reasion the function of the valves is to prevent the backflow of blood
