Control of blood glucose

• What happens if the bodies glucose level is too low?

  The receptors detect glucose level decrease.

  The effector(pancreas) releases glucagon.

  Stored glycogen in the liver is broken down into glucose and released into the blood.

  Control centre in brain compares stimulus to set point
• What happens when the glucose level is too high?

  Receptors detect an increase in glucose level

  The effector(pancreas) releases insulin

  Glucose removed from the blood and stored as glycogen in the liver

  Control centre compares stimulus
• What is Thyroxine controlled by

  Negative feedback
• What is blood glucose concentration monitored and controlled by?

  The pancreas
• What happens if the blood glucose concentration is too high?

  Pancreas releases insulin

  Insulin causes glucose to move from blood into cells

  In liver and muscle cells glucose is converted to glycogen for storage
• What is Type 1 diabetes

  Pancreas fails to produce sufficient insulin

  leads to high blood glucose levels

  Treated by monitoring blood glucose levels and injecting insulin when too high
• What is type 2 diabetes?

  Body cells losing the ability to respond to insulin

  Treated with carbohydrate controlled diet and regular exercise

  Have to take drugs to control levels
• What is a risk factor of type 2 diabetes?

  Obesity
