Homeostasis in my eyes

     Homeostasis is a very easy way of explaining how the body balances itself out; in scientific terms "Homeostasis is the ability to maintain a relatively stable internal environment in an ever-changing outside world. The process of Homeostasis contains chemical, thermal, and neural factors that interact.

     Receptors check out what the body is doing and responds to the changes. Once the receptors find what the body needs it "tells" the control center. The Control center receives the information from the Receptors and immediately reacts to the "value" of what the specific need is, after this job is complete with information the final step comes about. This final step is the Effectors, there job is to "read" the message from the Control center and break down what is needed for the body. With these three parts interacting a bigger picture comes in play. This "picture" is called Homeostatic mechanism, this is the process when homeostasis begins to tell the receptors what the stability is in the body. When this process is finished the receptors slowly shut down untill needed again, this is placing the body back in balance which is called Negative feedback. Negative feedback is what is supposed to happen through homeostasis. Rarely does positive feedback happen, Positive feedback only happens with a wound or during child birth.


Here is the lab that we did (better examples)
