Question

Compare the body cavity of frog and man?

Answer 1

Answer:

Frog is an amphibian organism, man is a mammal. Amphibians lack a diaphragm which in mammals separate the thoracic cavity from abdominal cavity.

Explanation:

Thoracic cavity in mammals is guarded by ribs (no ribs are there in frog). Diaphragm is a muscular partition between thoracic and abdominal cavities, that helps in breathing.

In absence of diaphragm torso of frog has a single cavity and floor of mouth cavity in frog helps in breathing.

Answer 2

Explanation:

A frog may also breathe much like a human, by taking air in through their nostrils and down into their lungs. The mechanism of taking air into the lungs is however sligthly different than in humans. ... The nostrils then close and the air in the mouth is forced into the lungs by contraction of the floor of the mouth.
