Homeostasis

Fill in the blanks using the drop-down menu. The process in which organ systems work to maintain a stable internal environment is called homeostasis. The regulation of your internal environment is done primarily through negative feedback, which is a response to a stimulus (or change) that keeps a variable close to a set value. So, how does our body regulate all these variables and compensate for changes in the environment? Well, it turns out we have tons of sensors in our body that monitor the temperature, salt composition of blood, blood pressure, osmolarity, and other things. These detectors signal the brain, or the control center, using an afferent signal when some value has deviated from normality and triggers an efferent signal that will try to restore that value to normal.
