Homeostasis

One thing i now know that i probably wont forget is the differences between positive and negative feedback loops. A positive feedback loop only stops when something occurs and a negative feedback loop shuts itself. 

Homeostasis keeps the body on track. Sensitive receptors monitor each condition under the homeostatic control. It monitors temperature, blood pressure, surcharge levels, osmolarity, PH and etc. If these are not in  the balanced range then the feedback loops kick in, called the corrective mechanism, which reverses the original change and brings the system back to normal. How this all works is the first thing is the stimuli, for example the body temperature rises above 37.5 degrees Celsius. Then the receptor detects it and sends a signal to the regulatory centre. Then the regulatory centre send that message to the effector, which is usually a muscle or a gland. Finally the response happens, for example sweat if its too hot. The body becomes normal again and if the feedback loop was a negative one it would shut off. This all happens continuously as we live our lives. An example of a positive feedback loop is labour.
