How are blood glucose levels regulated?

Answer 1

-After eating, blood glucose levels rise.

-This is picked up by the pancreas.

-Pancreas produces insulin.

-Insulin causes cells to remove glucose from blood.

-Removing glucose from blood causes blood glucose levels to fall.

Question 2

What happens when blood glucose levels are too low?

Answer 2

-If blood glucose gets too low, it is picked up by the pancreas.

-Pancreas starts to produce glucagon.

-Glucose that is stored in muscle and liver cells starts to return to the blood.

Glycogen ———->Glucose
Glucagon

-This causes blood glucose levels to rise again.
