why in frog and man different circuit system are present
Answers
Explanation:
The human has a double circulation system whereby the oxygenated blood is separated from the deoxygenated blood. This ensures that energy is not wasted in pumping deoxygenated blood back to the body.
The pulmonary circulation in human is at low pressure to protect the delicate tissues of the lungs whereas the systemic circulation is at high pressure to the rest of the body. This ensures that organs like brain get oxygenated blood on time to prevent fainting in humans.
Due to the difference in body and structure requirements the frog and the human need different circulatory systems.
Answer:
The major difference in a frog’s and a man’s circuit system is in their lungs.
They both inhale oxygen and release carbon-di-oxide.
There are differences in the way they breathe but. Man has a sheet of muscle called a diaphragm that is attached to the ribs and the bottom of the lungs.
The contraction of the diaphragm expands the chest cavity and the difference of air pressure gets sucked into the lungs.
Frogs, unlike men, don’t have a diaphragm.
