Blood glucose regulation

Glucose is needed by cells for respiration. It is important that the concentration of glucose in the blood is maintained at a constant level. Insulin is a hormonehormone: chemical messengers produced in glands and carried by the blood to specific organs in the body produced by the pancreas that regulates glucose levels in the blood.

How glucose is regulated

Glucose levelEffect on pancreasEffect on liverEffect on glucose level
too high insulin secreted into the bloodliver converts glucose into glycogen goes down
too low insulin not secreted into the blood liver does not convert glucose into glycogen goes up

Use the animation to make sure you understand how this works.

Glucagon – Higher tier

The pancreas releases another hormone, glucagon, when the blood sugar levels fall. This causes the cells in the liver to turn glycogen back into glucose which can then be released into the blood. The blood sugar levels will then rise.

Now try a Test Bite- Higher tier.
