Who knew that a frog’s body system is similar to humans? For example, their digestive system starts at the esophagus where the prey is swallowed wholly and enters the stomach, which is the first major sign of chemical digestion. Then the digested food travels through the small and large intestine (cloaca) and exits out the anus.
In addition, here are some interesting frog facts. Frogs breathe and drink through their skin, and their eyeballs are pushed into their head when they swallow a prey to help push the food down the esophagus!
Finally, I loved the Animals Unit and enjoyed dissecting the frog. Initially, I was confused about the location of each organ, but when I explored this amphibian, I had a better understanding of it. All in all, dissection is a great experience and I hope future students can do it as well.
