- DneostaSIS means maintaining a stable, approximately constant internal environment within an organism. O ose the external environment is constantly changing (temperature, chemicals, etc.), organisms must have a control system to detecting changes and responding to them.. Anything that must be maintained in the body within a normal range (the "set point") must have a control system. For example, body temperature, blood pressure, and blood glucose levels are all regulated. To cal Immmon ht 16. A homeostatic control mechanism consists of three parts. Fill in the blanks with the appropriate word for the analogy below. ast gool The variable or stimulus is the factor that is regulated (ex: room temperature / body temperature). A variable is like a teeter-totter. If it is perfectly balanced in the horizontal position, it is at the normal value called the ibeet (ex: 68° F/98.6° F).
