Frog Dissection

Evidence of Work

Introduction

  • What did you do: In this lab we disected a frog in order to gain a complete understanding of the internal and external anatomies of a frog. We acomplished this over one weeks time, dissecting or focusing on a few specific body system at a time.

  • What body systems did you investigate: The body systems we investigated were skeletal, muscular, circulatory, respiratory, digestive, reproductive, excretory and nervous systems.

Frog Information

  • What Phylum and class does the frog belong to: The frog is a member of the phylum Chordata and the class is Amphibia.

  • Characteristics of the Phylum Chordata: Chordates all have a hollow dorsal nerve cord, a notochord, and pharyngeal gill slits

  • Characteristics of the Class Amphibia: Amphibians all have the characteristics of being tetrapods (4 limbs) that facilitate moving about on land, thin scaley skin, they are Ectothermic, being gill and lung breathers , and they have a three-chambered heart with two atria and one ventricle

  • Write about 3 things you learned about how the frog body systems compare to humans:

  1. Overall the frog's body systems are very similar in comparison to humans with only some differences to accomidate the adaptations of each species.

  2. Both humans and frogs contain skeletal, muscular, circulatory, respiratory, digestive, reproductive, excretory and nervous systems. These sysytems also have many of the same organs and functions.

  3. The frogs body systems/ organs for these systems are in a smaller proportion. This is expected since the frog has a much smaller size compared to a human.

Reflection

  • Write about your most favorite and least favorite thing about the dissection: Honestly my favorite part of the disection was being done with it and getting to throw the frog away. Meaning that my least favorite part was having to disect the frog. I found all the information we learned fairly interesting but I did not enjoy having to cut up the frog.

  • What else do you want to know or are still curious about: I feel like we learned so much during this entire process that I don't really think I have any questions about the frog or its anatomies. The only thing I wonder about is how are the frogs killed and preserved so that we are able to use them for disection and experimentation

  • Write a reflection using two of the 6 C's. What C did you address during your dissection? What C should you work on: All in all this entire process was soemthing I will never forget and I feel like I learned so much. We acomplished all that was required of us in order to complete the experiment. We accelled in collaboration because my partner and I had to work well together in order to disect the frog and complete our packet. Something that we could have improved on is our critical thinking, or thinking outside of the requirements. I would say for the amount I hated cutting open the frog, I gained an equal amount of knowlege on the topic as well.
