HOMEOSTASIS
INTRODUCTION
‘Homeostasis’ refers to the maintenance of constant internal environment of the body.
Internal environment in the body is the extracellular fluid (ECF) in which the cells live. It is
the fluid outside the cell and it constantly moves throughout the body. It includes blood,
which circulates in the vascular system and fluid present in between the cells called
interstitial fluid.
If the internal environment deviates beyond the set limits, body suffers from malfunction or
dysfunction.
COMPONENTS OF HOMEOSTATIC SYSTEM
Homeostatic system - self regulating
operate in a cyclic manner
cycle includes four components
1. Sensors or detectors, which recognize the deviation
2. Transmission of this message to a control center
3. Transmission of information from the control center to the effectors for correcting the
deviation.
4. Effectors
