The amount of glucose, or sugar, in the blood must be kept within certain levels. This middle school Biology quiz looks at how the body controls blood sugar levels with hormones, and it concentrates on how insulin is used to lower the amount of glucose in the blood.

1.
Insulin is a hormone which means that it travels in the...
blood
urine
lungs
liver
All hormones travel in the blood to their target organ
2.
This is the organ that monitors blood glucose levels.
Pancreas
Liver
Brain
Kidney
The pancreas monitors blood glucose and releases insulin or glucagon if needed
3.
Insulin has this effect on blood glucose levels.
Increased
Decreased
Same
Increased then decreased
Insulin lowers blood glucose
4.
This is the target organ for insulin.
Brain
Liver
Lungs
Heart
Cells in the liver are stimulated to reduce the glucose concentration in the blood by converting it to glycogen
5.
Insulin is a hormone released from the...
liver
brain
pancreas
muscles
The pancreas is about 15 cm in length and situated between the stomach and the liver
6.
A typical situation for insulin release would be...
before a meal
during a meal
after a meal
during sleep
After a meal, you will have digested your food and blood glucose levels will be increased. This is the stimulus for insulin release from the pancreas
7.
Diabetes can be caused by a lack of...
vitamins
glucose
glycogen
insulin
Diabetics with type 1 diabetes have to inject themselves with insulin because their pancreas cannot make insulin
8.
Insulin exerts its action by causing glucose...
uptake
conversion
production
synthesis
It is changed into a chemical called glycogen which can be stored. Glucose is a soluble molecule and cannot be stored
9.
Glucose is removed from the blood by being taken up into cells in the...
lungs
liver
blood
kidneys
The liver has many other jobs - it produces cholesterol, urea and substances that break down fats. It provides the body's storage device for vitamins A, D, K and B12 as well as the glycogen produced when insulin reduces blood sugar
10.
Insulin is released when blood glucose levels are...
high
low
no different
constant
A different hormone (glucagon) is secreted when the glucose concentration in the blood falls too low
