The pictures on top are all related to homeostasis. Write down what you think homeostasis means.
Homo = same, Stasis = to remain still or steady
HOMEOSTASIS is the regulation of conditions inside the body to maintain a constant internal environment despite fluctuations in the external environment.
Humans have homeostatic control systems that regulate:
Body temperature
Blood pressure
Level of blood glucose
Levels and balance of respiratory gases in tissues.
Homeostatic control systems have 3 functional components:
A RECEPTOR - located in various organs (e.g. skin, eyes, brain) to detect a change / a stimulus
A CONTROL CENTRE - located in the brain to compare this change against the set point, and give out instructions to effectors.
An EFFECTOR: various organs that direct the appropriate response to correct the change.
