HOMEOSTASIS

Have you ever wondered why when it's really hot outside your body sweats, or when its really cold you shiver?

     Well that's a form of homeostasis taking place in your body. The human body has various ways of keeping warm or cool depending on its outside world conditions. Homeostasis is the ability for the body to maintain a relatively stable condition to keep all organs functioning properly with the changing environment both internally and externally. Along with organs functioning properly blood levels of vital nutrients must be present as well. These allow the heart activity and blood pressure within the body to react efficiently in order for blood to be propelled to all body tissues. The way in which our bodies talk in this specific condition is essential for homeostasis to occur. The nervous and endocrine systems are the key contributors to this situation by sending electrical impulses by nerves or blood borne hormones. Along with this there are 3 components that in themselves help control the homeostatic control mechanisms. The first component is the receptor, which starts the path of homeostasis by sensing the conditions of the environment and responding to the changes, this is known as the stimuli. The stimuli helps by sending information to the second component of this chain, the control center. The control center determines the set point ( level or range a variable will be maintained), it then analyzes the input it receives and determines the response or course of action. Finally the last component to this homeostasis path is the effector. The effector provides the means for the control center's response to the stimulus. From there either negative or positive feedback is distributed depending on the results of the response to the stimuli from the homeostasis mechanism.
