Question

Why three chambered heart of frog is not as efficient as the four chambered heart of birds and mammals?

Answer

◇In a frog, the heart is three chamberd. There is a single

ventricle and the oxygenated and deoxygenated blood get mixed before being pumped out of the heart.

◇In the Mammalian heart, the oxygenated and deoxygenated blood are clearly demarcated and no mixing takes place.

◇Thus a mammalian heart is more efficient than heart of frog.

Thank my answer and do follow ..

Answer 2

Answer:

Frogs have two atria, yet still only one ventricle. Two atria 's allow oxygenated and deoxygenated blood to be separated. ... The less efficient three chambered heart is adequate for these organisms to survive, as they still respire through the skin, allowing a less degree of oxygenation mechanisms within the blood system.
