What does the body balance? ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
How does the body keep balanced? ,[object Object],[object Object],[object Object],It works much like a thermostat in a house!
Feedback: Temperature ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Feedback: Glucose levels ,[object Object],[object Object],[object Object],[object Object],[object Object]
If there is too much glucose in the blood, Insulin converts some of it to glycogen Glycogen Insulin Glucose in the blood
If there is not enough glucose in the blood, Glucagon converts some glycogen into glucose. Glycogen Glucagon Glucose in the blood
Diabetes ,[object Object],[object Object],[object Object],[object Object]
Time Glucose  Concentration Meal eaten Insulin is produced and glucose levels fall to normal again. Glucose levels rise after a meal. Normal
Diabetic’s Response After Eating Time Glucose  Concentration Meal eaten Insulin is not produced so glucose levels stay high Glucose levels rise after a meal. Diabetic
