It is neccesarily because frogs are amphibians and therefore to be on land they need lungs to breathe
You need oxygen in your lungs in order to breathe. Without blood to transport it your lungs would have none and you wouldn't be able to breathe.
Because spiders breathe through spiracles on their abdomen, they are able to breathe in air and smoke as they do not have any lungs
Frogs breathe just like humans, taking in air through their mouths and exhaling it. They are also able to breathe through their skin.
You would not be able to digest or breathe through your lungs.
If you injure your lungs every badly you wouldn't be able to breathe.
no, they wouldn't be able to breathe.
Reptiles breathe air through their nostrils and their mouths into their lungs. They don't have gills and if they swim underwater they have to come to the surface to breathe.(Amphibians ( frogs, toads, salamanders, newts, and caecilians) are not reptiles. Most amphibians can accept oxygen from water or air through their skin. They can also pump air into their primitive lungs using their mouth or throat to force it down.)through their noseYes they do.

You can't - lungs are vital organs in humans that a person cannot survive without. We can supplement oxygen to lungs and help extremely damaged lungs function well enough to maintain life (sometimes), but you still have to have lungs to breathe and live.
Hi there,The most important thing about your lungs is that without them, you wouldn't be able to breathe
Snails and slugs have lungs, so they can breathe.
fish do not have lungs, so they are unable to breathe air as humans and mammals etc. do
When someone have cold then he is not able to get enough oxygen to his lungs so that's why its difficult to breathe
