In class on September 29, 2011, Dr. Rood measured his normal blood sugar level at 9:25 a.m. After the initial measurement, he ate a Snickers Bar and quickly drank a can of Sprite. He then recorded his blood sugar every 5 minutes of class (for a total of 10 measurements).  The results are shown in the graph above.
What caused Dr.Rood's body to return to the baseline of normal glucose levels? Blood sugar levels are regulated by negative feedback in order to keep the body in homeostasis.
