Controlling Blood Glucose

Controlling Blood Glucose

• Eating foods containing carbohydrates puts glucose into the blood from the gut.
• The normal metabolism of cells removes glucose from the blood.
• Vigorous exercise removes much more glucose from the blood.
• Excess glucose can be stored as glycogen in the liver and in the muscles.
• The level of glucose in the blood must be kept steady. Changes are monitored and controlled by the pancreas, uaing the hormones insulin and glucagon, in a negative feedback cycle.
• When blood glucose levels are too high, the pancreas secretes insulin. Glucose moves from the blood to liver and muscle cells, where insulin makes the liver turn glucose into glycogen.
• If blood glucose is too low, the pancreas releases glucagon, which turns glycogen into glucose in the liver, releasing glucose into the blood.
