This project was about homeostasis. Homeostasis is the balance in the body which regulates bodily functions. For this project, my group had to design an experiment that would test and show the process of the homeostasis of breathing. To do this, my group designed a test which involved 3 subjects, one of which a control, to perform physical activity and see the change in breathing rates that resulted.
The test involved checking breathing rates, running for 30 seconds, testing breathing rates, running for another 30 seconds, and then testing breathing rates until they returned to the original rate. The control subject did not run, as this was to get a baseline to what breathing rates do when no physical activity is performed. Our results found that due to physical activity, breathing rates will increase quickly, and then post physical activity, return to normal over a period of time.

Concepts
Homeostasis- the balance in the body which regulates bodily functions Inhalation- the process of inhaling, drawing air into your lungs Exhalation- the process of exhaling, pushing out CO2 from your body Control - something in an experiment which will give always give the same outcome, used for comparison to the variable you are testing, gives the output that is expected in the experiment Reflection
In this lab, I learned many things. One of which was how complex the body was and how homeostasis works. In our body, when something changes, for example we exert more energy due to physical activity, many systems need to change to the new situation. More oxygen needs to be brought into the body so breathing increases, blood flow is directed to the muscles, energy is used up, etc. Another thing I learned was how to create a scientific article. Even though we finished ahead of time, staying on task was an issue. We could have done better in regards to staying on task by focusing more and not going on our phones. Another area I can improve upon is trying to engage everybody so that everyone puts in equal effort and time. |
