Osmoregulation Feedback Loops
Human Biology (Year 12) - Maintaining Water Balance
What is the feedback loop for low plasma water levels?
What is the feedback loop for high plasma water levels?
What is the thirst reflex?
A decrease in the water concentration of the plasma (due to water loss), increases osmotic pressure, which in turn stimulates the thirst centre in the hypothalamus. This initiates the thirst response.
