Flowchart Glucose Regulation

Stimulus: Blood glucose level is above normal

Response: Beta cells of he pancreas produce insulin into the bloodstream

Insulin orders cells to take up more glucose (Eizadi, et al., 2013)

Blood glucose levels decrease to set point (Fagerholm et al., 2011)

Normal blood glucose level

Stimulus: Blood glucose level is below normal

Response: Alpha cells of he pancreas produce glucagon into the bloodstream

Glucagon orders cells to break down their glycogen to glucose (Suh et al., 2007

Blood glucose levels increase to set point (Yingjiang et al., 2011)
