Homeostasis-blood glucose after eating
Blood glucose levels rise
This is picked up by the pancreas
Pancreas produces insulin
Insulin causes cells to remove glucose from blood
Liver and muscle cells can convert glucose into glycogen and store it
Removing glucose from blood causes blood glucose levels to fall
What happens when blood glucose gets to low ?
If blood glucose gets too low it is picked up by the pancreas
Pancreas starts to produce glycogen
Glucose that is stored in the muscle and liver cels starts to return to the blood
This causes blood glucose leves to rise again
