Random anatomy question

Postby Litoria Alex » Thu Jan 26, 2012 7:38 pm

Bit of a strange question but it came to me as I was watching my froggies the other day. Why do frogs' throats go up and down like they are breathing? Is it their heart beat? Just curious if anyone knew:)

Yeah it's weird though but also handy to check if they're still alive;) I also wonder if they absorb air through all their skin or just certain areas. Frogs are a lot more fascinating than many people think!

I found a teaching aid website and it said....
http://spikesworld.spike-jamie.com/scie ... thing.html
"Look at the frog in our terrarium. See his nostril vents near his nose? (Actually, frog's noses are called "snouts.") Now look at his throat. See how it goes up and down? It acts sort of as a pump. The frog takes in air, and the floor of his mouth raises and lowers, causing the pumping effect."

If this is correct from the sound of it has a similar function as our diaphragm instead of 'pulling' air in and 'pushing' air out the frog will 'push' air in and 'pull' air out

Also found this one in my search...

"Q. How do frogs breathe?
A. Most frogs and toads breathe (and take in moisture) through their skin through a process called cutaneous gas exchange, but they also have lungs with which they breathe. During the time they stay submerged under water or buried in soil (such as during hibernation) they ONLY breathe through their skin.

Q. How do frogs make their calls?
A. They squeeze their lungs with their nostrils and mouth shut. Air flows over their vocal chords and into their vocal sacs. Vocal sacs are located on their throat, and you can see it blow up like a balloon. S some frogs can make noises without vocal sacs."
