Question

How does the body cavity of the frog differ from that of man?

Answer 1

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.
