Frog Dissection

        On Tuesday, we dissected a male frog and finished dissecting on Wednesday. First, we cut open the frog carefully and had to pin back its skin. I was really amazed at how the frog had so many thick protective layers protecting the insides of the frog. I knew that there had to be layers of skin, fat, etc. protecting the frog's organs, but what amazed me were how thick they were and how many there were. My group had a male frog, so we didn't have any eggs to remove, but we did have loads of fat bodies to remove. Covering many of the organs in my frog was peritoneum. I found a lot of it near the heart than any of the other organs. Also, as soon as we opened up the frog, we saw the liver. I just thought that the liver would be one whole piece instead of three seperate pieces being everywhere. What amazed me was the color of the frog's gall bladder. I thought it would be a brownish colors like the liver/lungs, but it was green. Another thing that surprised me was the spleen. I never even knew frogs had an area for holding blood until this dissection.






Here are some of the parts of the frog we saw.
   
        


 A frog's body isn't as complexed as a human's but it is quite similar to our body. We have most of the same organs like the frog. Although, they might not look alike, they do the same things and function the same way. For example: the heart pumps blood, the liver produces bile, the gall bladder stores the bile, and many other organs like that. We have the same systems that work together to create a specimen. I really liked how the small intestine and the large intestine were laid out, just like humans. I could just imagine the food going through the frog's digestive system. I just wish we could've saw its brain and its heart actually pumping. That would've been so cool! This frog dissection was really amazingly awesome, and I hope we do more things like this in the future!
