What is homeostasis?
- Regulation of internal conditions of a cell or organism to maintain optimal conditions
Why is homeostasis important in body? (1)
- Maintain optimal conditions for enzymes action & all cell functions
In human body, these include control of:
- Blood glucose con
- Body temp
- Water levels
These automatic control systems may involve nervous or chemical responses
All control systems include:
- Receptors – cells which detect stimuli (changes in environment)
- Coordination centres eg brain, spinal cord & pancreas – receive & process info from receptors
- Effectors, muscles or glands – restore optimum levels
