Homeostasis Flashcards
What is Homeostasis
it is the regulation of the internal conditions of a cell or organism to maintain optimum conditions for function in response to internal and external changes
What does Homeostasis do?
Maintains OPTIMAL conditions for enzyme action and all cell functions .
What does homoeostasis control
1.blood glucose concentration
2.body temperature
3.water levels
these automatic control systems may involve nervous responses or chemical responses
All control systems include what and explain the feature with the function
cells called receptors, which detect stimuli (changes in the
environment)
* coordination centres (such as the brain, spinal cord and pancreas)
that receive and process information from receptors
* effectors, muscles or glands, which bring about responses which
restore optimum levels
