Question

hi friends please tell me four chambered heart in mammals is efficient than three chambered heart of reptiles. give reason.?​

Answer 1

Explanation:

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. The four-chambered heart of birds and mammals evolved independently from a three-chambered heart.

Mammals and birds have the most efficient heart with four chambers that completely separate the oxygenated and deoxygenated blood; it pumps only oxygenated blood through the body and deoxygenated blood to the lungs.In a four-chambered heart, oxygenated blood carried by the left side of the heart is more effectively separated from deoxygenated blood carried by the right side, which assists in more efficient movement of oxygen around the body.

OR

In short

Birds and mammals, however, have a fully septated ventricle--a bona fide four-chambered heart. This configuration ensures the separation of low-pressure circulation to the lungs, and high-pressure pumping into the rest of the body.
