endocrine functions of the pancrease

In normal persons, blood glucose level is controlled within a narrow range.

In the early morning after overnight fasting, the blood glucose level is low ranging between 70 and 110 mg/dL of blood.

Between first and second hour after meals (postprandial), the blood glucose level rises to 100 to 140 mg/dL.

Glucose level in blood is brought back to normal at the end of the second hour after the meals.

Blood glucose regulating mechanism is operated through liver and muscle .

This is mainly by the influence of the pancreatic hormones – insulin and glucagon.
Many other hormones are also involved in the regulation of blood glucose level.

Among all the hormones, insulin is the only hormone that reduces the blood glucose level and it is called the
antidiabetogenic hormone.



The hormones which increase blood glucose level are

called diabetogenic hormones or anti-insulin hormones.Necessity of Regulation of Blood Glucose Level:

Regulation of blood glucose (sugar) level is very essential because, glucose is the only nutrient that is utilized for energy by many tissues such as
