Homeostasis and response

• What is the definition of homeostasis?


  Homeostasis is the regulation of internal conditions in an organism or cell.
• Why is homeostasis important for organisms?


  It maintains optimal conditions for enzyme activity and supports all cellular functions.
• What are the key parameters controlled by homeostasis?


  • Blood Glucose Concentration
  • Body Temperature
  • Water Levels
• How does blood glucose concentration relate to homeostasis?


  It regulates energy supply to cells.
• Why is body temperature important in homeostasis?


  It maintains a constant temperature for metabolic processes.
• What role do water levels play in homeostasis?


  They balance fluid levels in cells and tissues.
• What are the components of control systems in homeostasis?

  • Receptors: Detect stimuli or changes in the environment.
  • Coordination Centres: Process information from receptors (e.g., brain, spinal cord, pancreas).
  • Effectors: Muscles or glands that carry out responses to restore optimal conditions.
• What is the function of receptors in homeostasis?


  Receptors detect stimuli or changes in the environment.
• What are coordination centres in the context of homeostasis?


  They are areas that process information received from receptors.
• What is the role of effectors in homeostasis?


  Effectors carry out responses to restore optimal conditions.
