examples of hemeostatic control systems:

• 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…
