Answer 1

when frogs undergo aestivation their body respire by skin and not by lungs

Answer 2

Hey!!

In some organisms like frog, they breathe through skin sometimes but we humans use our pair of lungs for gaseous exchange.

Lungs have alveole and bronchioles which helps in gaseous exchange but not the skin.

Humans are adapted to breathe from lungs.
