why in frog and man different circuit system are present
Answers
Answer:
"A frog’s heart has only three chambers, consisting of two atria and one ventricle. The single ventricle receives both deoxygenated blood from the body tissues via the right atrium and oxygenated blood from the lungs and skin via the left atrium." (Source: The Cardiovascular System: Differences in Anatomy and Physiology Between Humans and Frogs)
The human heart has 4 chambers: 2 atria and 2 ventricles. The right side of the heart receives blood from the body and the left side of the heart pumps blood out to all of the body. Normally, there is no mixing of deoxygenated and oxygenated blood i...

The requirement in human and frog need different circulatory due to difference in body and structure requirement.
EXPLANATION:
The circulatory system in human maintains the oxygenated blood being separated from deoxygenated blood. The gas exchange takes place inside the lungs.
This process proves that human lungs are more efficient from frog lungs. Diaphragm is present in human lung but not in frog lung. In Frog 'gas exchange' takes place through moist permeable skin where human have 'dry skin' that is 'impermeable' to gas exchange.
