Blood sugar level song
(To the tune of `if you're happy and you know it'.)
When we eat, our blood-sugar level goes up,
Insulin's secreted by the pancreas,
The liver detects the insulin,
It knows to let the glucose in,
And it is stored as glycogen in the liver.
Blood-glucose level goes down with exercise,
And the pancreas some glucagon provides,
The liver finds the chemical,
Turns glycogen to soluble...
...glucose, And back into the bloodstream it arrives.
