  2. 2. 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: ◦ Skin ◦ Lungs ◦ Lining of mouth
  3. 3.  Frog also respires through skin.  This is called as cutaneous respiration in frog.  This is an secondary respiratory system.
  4. 4.  Cutaneous respiration occurs while frog is in hibernation (winter sleep) or completely submerged.
  5. 5.  Frogs must keep their skin moist to allow efficient respiration through skin.
  6. 6.  Frog skin has mucus glands which secrete mucus onto the surface of skin when they are out of water.
  7. 7.  The oxygen is absorbed from water through skin using special blood vessels.
  8. 8.  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.
