Homeostasis is the way our body maintains balance in all ways. Out body is constantly changing, the outside variables like temperature, the food we consume, and the air we breathe all changes. To compensate for the change out body regulates different chemicals and rates. Some ways our body maintains homeostasis is through, Breathing rate, heart rate, hormone levels, ph levels, blood pressure and more.
Out group studied how the body maintains a safe flow of blood to the muscles. When your body exercises the muscles need more oxygen and nutrients to function. We found that the human body exercises or uses muscles the heart rate is increased. This increase sends more blood in and out of the muscles, thus increasing the flow of the vital resources the muscles need. Our experiment was conducted using two subjects, we started by measuring the resting heart rate of both. Once we had a baseline heart rate, both subjects would complete 15 pushups as a way to stimulate physical activity. Right after 15 pushups we measured the heart rate again. And once again 5 minutes later for a control. We found than on average out body increased the heart rate by 20 bpm to insure the muscles had enough resources.
As a finial evidence of work for this project we created a final poster. This poster included all the information we found and how we got it. This includes procedures, graphs, and tables.

Homeostasis: A state of balance the body gains to survive and function correct.
Feedback Mechanisms: A way for the body to measure if it is in homeostasis and how much to change to achieve it.
Scientific Method: A method of explaining and establishing facts through testing.
Independent Variable: A variable that is manipulated by the researcher and not dependant on anything.
Dependent Variable: A variable that is dependent on another Variable, commonly the independent variable.
Constant: The constant is the part of the experiment that does not change.
Experimental: Conditions to collect observations from an experiment.
Hypothesis: An educated guess aimed at defining your understanding before experiments are conducted.
Reflection
I very much so enjoyed this project, it taught about how and why your body changes and adapts. Me and Kian where left to complete this project by our self. Our third member Arnesy was unable to complete what he signed up for, he left Kian and I scrambling the night before finishing his part. Kian and I both agreed to take his name off the paper. He was not present to help and didn't step up and complete what he as assigned too. I could have worked on my communication skills, maybe if I was a little more direct and demanding the work would have been done. But I also worked really well with Kian and we completed the whole assignment efficiently. Over this project was a learning experience in two ways. It taught me to be more direct with people who maybe dont try, and that the body maintains homeostasis very efficiently.
