Skin is an accessory organ of respiration in

Explanation

All options are explained below: a) Humans: In humans, the skin can play a limited role in respiration, but it is not considered an accessory organ for this purpose. The primary organs of respiration in humans are the lungs. b) Frog (Correct Option): In amphibians like frogs, the skin plays a significant role as an accessory organ of respiration. Frogs can exchange gases (oxygen and carbon dioxide) through their skin, especially when they are in a moist environment. This cutaneous respiration is an important part of their respiratory strategy, particularly when they are out of the water. c)Rabbit:In rabbits and most mammals, the skin is not a significant accessory organ of respiration. The primary respiratory organs in mammals are the lungs. d) Lizard:Lizards, like frogs, can utilize cutaneous respiration to a certain extent. However, the extent to which the skin functions as an accessory organ of respiration can vary among different species of lizards. Correct Option: B. Frog Summary: The skin serves as an accessory organ of respiration in frogs, especially when they are in a moist environment. It allows for the exchange of gases through the skin. While some other organisms, like lizards, can also use cutaneous respiration to some degree, the role of the skin as an accessory organ in frogs is well-established.
