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.
