Question

is there any connection with four chambered heart and warm blood in bods and mammals?​

Answer 1

Answer:

The discovery has shed light on how cold-blooded birds and mammals became warm-blooded. ... However, birds and mammals have a fully septated ventricle-a bona fide four-chambered heart, which ensures the separation of low-pressure circulation to the lungs, and high-pressure pumping into the rest of the body.
