Frog Dissection

As the black frog was layed out in front of me, I wondered what it was like inside of it. As my group made its first incision, we quickly realized we had a boy. The way we could tell is that it did not have eggs or giant oviducts. Shortly after we found out its gender, we saw three big brown lobes covering all of the other intestines. This was the liver and above it was the heart. I hope that word is fimiliar to you because it is what keeps us alive. It pumps blood all throughout the body for us and the frog. Around the frog were yellowish and sphagetti like organs. This was the fat bodies which stored energy for the frog. I am sure that a frog needs a lot of that because it hops and climbs constantly. Of course, the frog has a stomach but not extremly big. I find that wierd because frogs swallow their food whole because they have no teeth. When they swallow food it goes down the esofagous and through the intestines. When all of the food exits it goes through the cloaca and out through the anus. That was the dissection of the frog in my science class.
