A couple of days ago in science class, we did a really cool dissection. A frog dissection. The frog was bigger than I expected, it was about 8 inches long and 5 inches wide. The pattern on its stomach was really cool, it had a cream color back round and light gray leopard spots on it. When I made the first cut, it thought it would be as thick as human skin, but it was like cutting fabric. When my group mates pinned the skin down, when i was cutting the muscle, it was like cutting a rubber band, but more fabric like, such as the skin. When we fully pinned down everything, we got our first glimpes at the frogs insides. You could easily the liver, (the three lobes) and the stomach, (the tube like organ). We had a chubby frog so the spagetti like fat bodies, were every where. Pulling out each and every fat body took longer than thought. Next we cut out the liver, which was very hard. We saw the little gallbladder and we popped it, we saw the bile in it excrete out. then we saw the jumbled brain like small intestine. We took that out and measured it, at its full lengh, it was longer than the lengh of the frog! We cut open the stomach to see what it last ate, nothing was in there. then we took out all the organs we already saw, and I located the spine. Someone else located the spleen which was read and full of blood. Finally time was up and the dissection was done. that was the most funnest, dissection ever.
