Controlling Blood Glucose

Controlling Blood Glucose

Insulin and glucagon control blood glucose level

1) Eating foods containing carbohydrate puts glucose ( a type of sugar) into the blood from the gut.

2) The normal metabolism of cells removes glucose from the blood

3) Vigorous exercise removes much more glucose from the blood.

4) Levels of glucose in the blood must be kept steady. Changes in blood glucose are monitored and controlled by the pancreas, using hormones insulin and glucagon.

Blood glucose level too high- insulin is added

Blood with too much glucose-> Insulin secreted by the pancreas-> too much glucose, but insulin as well-> the glucose is removed by the liver and the insulin makes the liver turn glucose into glycogen-> blood glucose reduced.

Blood glucose level too low- Glucagon is added

Blood with too little glucose-> glucagon secreted by the pancreas-> too little glucose, but glucagon as well-> glucagon makes the liver turn glycogen into glucose-> glucose added by the liver, blood glucose increased.

Type 1 diabetes

1) Type 1 diabetes is a condition where the pancreas produces little or no insulin. The result is that…
