What is cutaneous respiration
Cutaneous respiration is form of respiration in
which gas exchange occurs across the skin.
Respiration in frogs
o Tadpoles use gills to respire.
o Frogs don't have gills and they
have to use another factors for
respiration such as:
◦ Lining of mouth
Frog also respires through skin.
This is called as cutaneous respiration in frog.
This is an secondary respiratory system.
Cutaneous respiration occurs while frog is in
hibernation (winter sleep) or completely
Frogs must keep their skin moist to
allow efficient respiration through skin.
Frog skin has mucus glands which secrete mucus onto
the surface of skin when they are out of water.
The oxygen is absorbed from water through skin
using special blood vessels.
Frogs are common animals we see around us.
But they are special because they live both in
land and water.
Frogs can live in water though they are not
having gills because of cutaneous respiration.
Cutaneous respiration is nothing but
respiration through skin in water.
