Frog Dissection

In class, we dissected a frog named Wendall. First we cut off the skin then had to cut off the muscle under it, while breaking bones in the process. Since it was a female, we took out the eggs. We also looked at the heart which was a clear sac like organ. When the frog breathes, it expands like so:

Lower, was the liver, (when you cut it out, it smelled really bad.) Under the liver was a green little sac, which was the gall bladder. The liver creates bile and the gall bladder stores it. The stomach was next to the liver, and sometimes when you cut it, you can see the frogs last meal. Here is a diagram:

The frog's digestive system and respiratory system are a lot like a humans, with minor changes. When we cut the frog open, I almost immediately knew where everything was. The frogs skin and muscle was very thin, and if you looked on the inside, you can see the blood vessels. We also noticed that in the liver took up a great part of the frog, besides the eggs which also took up the other side. I wondered, why did the liver have to be so big? After we removed the liver and eggs, there wasn't much left. (Sorry about the way this section is spaced out, my computer is having issues.)

I also remember, how we thought the small intestine was the stomach, so we cut it up. We didn't get a chance to get a good look at the intestine though, so I don't really remember what it looks like. After we cut what was actually the stomach, there was nothing in there. It looked like a stitched up kidney bean.

Here is an online dissection game:

This game is online dissection in which you then have to identify the individual parts.
