Question

Skin is an ideal respiratory organ in frog because it is

• A. Highly vascular
• B. Kept moist
• C. Devoid of hair and scales
• D. All the above

Answer 1

The correct option is D All the above

The skin of the frog has a role to play in the respiration process. It acts as the aquatic respiratory organ, as oxygen gets diffused through the skin when a frog is in water. The characteristics of the skin such as the mucous glands which keep the skin moist and the highly vascular nature and absence of hair or scales also help in respiration. This type of respiration is called cutaneous respiration.

So, the correct answer is 'All of the above'.
