the maintennce of a constant internal environment

examples of hemeostatic control systems:

  • maintaining blood glucose levels
  • thermoregulation
  • osmoregulation

Homeostatic Processes

all processes involve:

  • detector: detects stimuli
  • coordinator: coordinates response
  • effector: carries out the response
    • either muscles or glands
  • a stimulus is a change in the level of the factor being controlled
  • the detector monitors the factor being controlled
  • the detector senses change and informs the coordinaor which receives and controls information from the receptor
  • the coordinator triggers an appropriate method for correcting the devation
  • the coordinator communicates with one or more effectors to carry out the corrective procedures
  • once the factor returns to normal, the information is bed back to the…
