What is Homeostasis
A stable internal environment Dynamic state of equilibrium Essential for normal body functioning Essential to sustenance of life Imbalance =>>> Disease
3 of 9
Components of Homeostatic Regulation
Receptors Control Centre Effector
4 of 9
Receptor
Responds to stimuli (changes) Informs the control center Via the afferent pathway
5 of 9
Control Center
Determines set point Analyses information Determines appropriate response
6 of 9
Effector
Provides a means for response to the stimulus > Receives information from control center via efferent pathway
7 of 9
Negative feedback
Most common mechanisms Shuts off the original stimulus Or reduces its intensity Works like a thermostat
8 of 9
Positive Feedback
Increases the original stimulus Pushes the variable farther Reaction occurs at a faster rate E.g. Blood clotting and Childbirth
