Respiratory System in Frogs -
Respiratory System in Frogs
- Frogs respire on land and in the water by two different methods
- In water, skin acts as aquatic respiratory organ (cutaneous respiration).
- Dissolved oxygen in the water is exchanged through the skin by diffusion.
- On land, the buccal cavity, skin and lungs act as the respiratory organs.
- The respiration by lungs is called pulmonary respiration.
- The lungs are a pair of elongated, pink coloured sac-like structures present in the upper part of the trunk region (thorax).
- Air enters through the nostrils into the buccal cavity and then to the lungs.
- During aestivation and hibernation, gaseous exchange takes place through skin.
-
Tadpole are completely aquatic. They respire through gills.
