Yes, they do.
I think it involves the Kidneys
Yes they do. They have kidneys just like us.
The skin.
No, amphibians do not need to have there skin wet at all times. Most amphibians can be in and out of water.
Because amphibians need to be moist.
Amphibians breathes through their skin, they accumulate enough air from the moist on their skin. If there is no moist, they will die.
No, amphibians don't need milk. Since they can't produce any, they wouldn't have survived if they needed any.
Mesonephric kidneys are the primitive excretory organs found in fish and amphibians, while metanephric kidneys are the more advanced excretory organs found in mammals, including humans. Metanephric kidneys filter blood to produce urine through nephrons, while mesonephric kidneys mainly function to remove waste products from the blood.
Amphibians can absorb oxygen through their skin - reptiles need to physically breathe.
Frogs are amphibians, and amphibians need to keep their skin moist, and rain helps with that.
Hello,the answer to this is quite easy, so I'll try and explain it as simple as I can.So, us humans need 'oxygen' to live right? We also need heat. Amphibians are different to us, their bodies function differently, so they need other resorces to keep them functioning.Amphibians need oxygen and heat, which every living thing needs. But amphibians need water or to be near water is because they have little holes in there body, these holes suck up water to keep them moist, and cool from the harsh weather. Hot or cold, they need to stay moist or else there kidneys stop and lungs break down, kind of like a car.I hope I answered your question.
Horses are big animals, but their kidneys work in the same way as other kidneys work. The kidneys work by filtering out what the body does not need.
