Respiratory System in Frogs MCQ - Practice Questions with Answers

 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.
