Admin Do fish and reptiles have lungs?
In air-breathing fishes and amphibians, there may be separate RRG for gill and lung ventilation. There is some evidence for multiple RRG in reptiles. Both amphibians and reptiles show episodic breathing patterns that may be centrally generated, though they do respond to changes in oxygen supply.
Do amphibians and fish have lungs?
Most amphibians breathe through lungs and their skin. Tadpoles and some aquatic amphibians have gills like fish that they use to breathe. There are a few amphibians that do not have lungs and only breathe through their skin.
What do fish amphibians reptiles birds and mammals have in common?
Fish, reptiles, amphibians, birds and mammals all have bones. Fish, reptiles and amphibians are cold-blooded animals. Scientists believe that fish were the first animals to develop bones. Some primitive fish, like sharks, have skeletons made out of a tough material called cartilage, but all the rest have bones.
Do reptiles and mammals have lungs?
Terrestrial vertebrates (amphibians, reptiles, birds, and mammals) use a pair of lungs to exchange oxygen and carbon dioxide between their tissues and the air.
How are amphibians different from reptiles?
Reptiles have scales, and their skin is dry. Amphibians do not, and their skin is often moist with mucus, which keeps them from drying up. Reptiles hatch from eggs that have a protective outer layer such as a brittle or leathery shell.
Do reptiles have lungs?
Unlike amphibians, reptiles breathe only through their lungs and have dry, scaly skin that prevents them from drying out.
Why do scientists classify fish amphibians reptiles birds and mammals together?
An organism’s body structure is its basic body plan, such as how its bones are arranged. Fishes, amphibians, reptiles, birds, and mammals, for example, all have a similar body structure—an internal skeleton with a backbone. This is why scientists classify all five groups of animals together as vertebrates.
Which animals have lungs for breathing?
Reptile Lungs Reptiles don’t have diaphragms to inflate their lungs; most expand their body walls and rib cages to take in air. Crocodiles and alligators inflate their lungs via a special muscle attached to their livers. Reptiles with lungs include crocodiles, alligators, turtles, tortoises and snakes.
