Question

why it is essential to seprate right and left side of heart in birds and mammals​

Answer 1

Answer:

In mammals and birds, the heart is also divided into four chambers: two atria and two ventricles, as illustrated in (Figure)d. The oxygenated blood is separated from the deoxygenated blood, which improves the efficiency of double circulation and is probably required for the warm-blooded lifestyle of mammals and birds.
