Organ and Organ System Relationship
Each organ in a organ system is important to the function of the system as a whole. In the same way, each system is important to the function of the frog as a whole because each system plays a part in keeping the frog alive and functioning. For example, if you look at the digestive system, the stomach is just as important as the large intestine because they both deal with digesting and moving the food in the frog. Both organs are part of the same system however, they perform different functions. There is a similar relationship between the various systems because each one depends on the others to carry out its function. It wouldn't matter how well the digestive system worked if the excretory system didn't get the waste from the digestive system out of the body. All of the organs and systems that make up the frog rely on each other and they all play a part in the healthy life of a frog.
How Are We Structurally Similar To Frogs?
Humans and frogs are structurally similar because we both have things such as a skull, spine, and livers. The skull protects the brain in both humans and frogs. The size of the brain and skull is drastically different but the skull performs the same function of protecting the brain from physical damage. Humans and frogs both have spines which run up their backs and support their bodies. Spines are very important to our structures and act like a giant support beam in a building. The livers in both frogs and humans perform the same function of filtering their blood. There is a slight difference in the fact the human livers have 4 lobes whereas frog livers only have 3. Humans and frogs have many of the same organs however, they are obviously on a smaller scale in frogs and are different than humans.
Reflection
I think this activity was helpful because it helped me to understand how the different organs work both individually and as part of a system. I liked the hands-on aspect of this activity because we got to move things around in the frog, poke and prod the different layers and muscles, and just see what the inside of an organism such as a frog looks like. It was helpful that we were given 3 days to work with the frog and actually take the time to go through the activity and get all of the pictures we need. In a lot of the past labs we have rushed through them in a day or two and I haven't really learned while we were doing it because I was too focused on getting the necessary information for the charts and questions. This time, there was no charts or reflection questions to fill out, instead we made this poster. I feel like I can better display my knowledge and understanding when we do projects like this one and the organelle campaign rather than labs with questions to answer and a very structured activity. However, it was a pain to transfer the pictures from my phone to the Chromebook, and then to the Smore because it was a lot of steps and kind of annoying. It wasn't that bad though it was worth it because I learned a lot from this activity. This activity helped me learn about science because I could physically see how the various systems in a frog would work and function together and I could look at it and say "There's the heart of the frog" and hold it instead of looking at a diagram on my Chromebook. Science is something that I think you can always learn more about even if it is just little things. I learned more about big concepts like organ systems and life in general through this activity.
