Question

Reptiles Breathe through
A) Gills
B) Skin
C) Lungs
D) None of the above

Answer 1

Hint: Reptiles are group of cold-blooded animals. They have skins covered with small hard plates is called scales and lay eggs. Reptiles crawl or moves on their belly or on small short legs (such as a lizard, snake, crocodiles).

Complete answer:
Reptiles are turtles, snakes, lizards and crocodiles. reptiles and amphibians breathe only through their lungs and they have dry, scaly skin that prevents them from drying out.

Reptiles are called herpetofauna or “herps” for short. All of the herps are “cold-blooded”, which means that they lack an internal thermostat. Instead of this, they must regulate body heat through their interactions with the environment. For example, A turtle warms itself by basking in the sun and a lizard can regulate its temperature by shutting and moving in and out of cover.

The respiratory organ present in reptiles is the lungs. The surface area of lungs is greater than amphibians for greater exchange of gases. In many reptiles, tiny alveoli are also present which brings about the diffusion of gases. The skin is used as a respiratory organ in earthworm. Frogs breathe through moist skin in water. Gills are the respiratory organs for the animals dwelling in water like fishes.

Thus, the correct answer is C i.e Lungs.

Note: Human beings and mammals have lungs for respiration. Most of the reptiles have three chambers heart that has two atria and one partially divided ventricle but not all the reptiles have a three-chambered heart. Crocodilians have a four-chambered heart just like mammals and birds. However, their four-chambered heart and three chambers are act as heart during dives.
