During hibernation, cutaneous respiration occurs in the frog, i.e. it respires through its moist skin or integument. The skin is permeable to respiratory gases and carries oxygen to the body cells for respiration.
Breathing during hibernation
We all know that frogs undergo hibernation. Now we will know how do they breathe during hibernation.
- Frogs spend the coldest times of the year by hibernating inside the mud or hide within rotten heaps of leaves.
- They receive their necessary oxygen through their skin. This process is known as cutaneous gas exchange.
- The skin of the frog is used to soak in the oxygen their bodies require.
- When frogs hibernate, they use the skin for breathing.
- Damp skin is mandatory for subcutaneous gas exchange.
- If the frog’s skin gets dried up, it will no longer get any oxygen to take in.
