Question

One of the following is a difference between pulmonary respiration of frog and human.

• A. Diaphragm and ribs play role in breathing
• B. Lungs are respiratory organs
• C. Respiration occurs due to pressure gradient
• D. None

Answer 1

The correct option is A Diaphragm and ribs play role in breathing

Frogs are the amphibians and humans are the terrestrial mammal. Due to different habitat there are differences in the respiratory systems. Firstly the humans breathe exclusively through their lungs, whereas frogs use their lungs only for a part of their respiratory process. Secondly, humans use their diaphragm muscle to contract the diaphragm but it is absent in frogs. Thus, the correct answer is option A.
