Document Summary

For adequate breathing and gas exchange in the lungs. These are the acceptable ranges necessary for life. The ability of the body to maintain relatively stable internal conditions even though there is continuous change in the outside world. It is not completely unchanging, it is a dynamic state, meaning it changes, but within steady narrow limits. Heart activity/blood pressure monitored and adjusted as needed. They send input to the control center along the afferent pathway to the control center. Determines the set point (the level or range at which the variable is to be maintained) Sends output information along the efferent pathways to effector. The means for the control center"s response to the stimulator feeds back to reduce the stimulus effect and returns the variable to homeostatic level. The body keeps the internal state in balance by: Constantly monitoring and regulating all the factors that can change (variables) These mechanisms reduces or shuts off the original stimulus.
