Frog Dissection

       In my science class, we finished the body systems unit, and to end it, we dissected frogs. When we got our frogs, we put on our gloves, and safety goggles and took out the dissecting tools. We used the scissors to cut through the layer of skin, and then the muscle underneath it. We pinned that back, and then looked inside the frog. We saw alot of eggs, which looked like small black beads. When I saw the eggs, I knew that our frog was female. We then had to remove all the eggs to see the other organs. After we did that, I had to break the frogs chest bones to see the heart. The heart in our frog was small, and red with a white film over it. Directly under the heart is the liver, which looked like a large brown three leaf clover.  Under the liver were the lungs and the gallbladder. The lungs were red and shriveled up, and the gallblader was dark green and small. It was next to the left lung. Below the liver was the stomach. The stomach took up most of the inside of the frog, and was a peach color. We cut out the stomach to see if there was anything in it, but there wasn't so we can assume our frog didn't eat before it died. Our frog also didn't have any fat bodies, so it probably just got out of hibernation before it died. On the sides of the frog, under where the eggs used to be were the ovaries. They were peach in color, and looked like ramen noodles packed closeley together. Connecting to the end of the stomach was the small intestine, which was slightly covered with a green substance that looked like swamp muck. The large intestine connected to the end of the small intestine, and ended at the cloaca which is like the anus.

           This dissection showed me that our body's organ systems aren't all seperate.In the frog, every body part was connected to something else. It also really made me see how similar a human body is to a frog's body. The dissection showed me that if you're missing one organ sytem, you're body won't run properly.
