Learning objectives – to learn how the blood glucose is controlled in the

                                           body and what can happen if it goes wrong.
When you consume carbohydrates, the body breaks it down into simple

sugars such as glucose. Therefore the body releases hormones to control the

levels. When the body is in-between meals and the glucose levels get too

low, then the body can also release hormones to increase the blood glucose

levels.

 

When you eat:


The blood glucose level increases, this is sensed in the body causes a

hormone called insulin to be released The hormone insulin stimulates the

liver to take up the glucose and convert into a molecule called glycogen,

which is a storage molecule.

 

Insulin is secreted by the pancreas and ensures the blood glucose level

does not get too high.

 

When you are not eating:

The blood glucose levels decrease and therefore a hormone called glucagon

is released.

 

Glucagon causes the liver to break down glycogen molecules back into

glucose and is released back into the blood Glucagon is secreted by the

pancreas and ensures the blood glucose level does not get too low.
