NEET BIOLOGY

Detailed explanation-1: -Amphibians live in both water and on land; amphibian larvae are born and live in water, and they breathe using gills. The adults live on land for part of the time and breathe both through their skin and with their lungs.

Detailed explanation-2: -Most amphibians undergo metamorphosis, during which they change from an aquatic animal that breathes through gills to an adult that may have gills or lungs, depending on the species.

Detailed explanation-3: -How do amphibians breathe? Most amphibians breathe through lungs and their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (If they get too dry, they cannot breathe and will die).

Detailed explanation-4: -Meet the Amphibians As the earliest four-legged descendants of fish, they begin their lives in water, using gills for breathing. In adulthood, they retain the ability to live in water, as they can absorb oxygen through their skin. Most metamorphose into land dwellers, as well, and develop lungs for breathing on land.

Detailed explanation-5: -Most adult amphibians can breathe both through cutaneous respiration (through their skin) and buccal pumping – though some also retain gills as adults. Amphibians have primitive lungs compared to reptiles, birds, or mammals. This means that they deal with slow diffusion of oxygen through their blood.
