5.3.2 - Control of blood glucose concentration Flashcards
(10 cards)
What gland monitors and controls blood glucose concentration?
Pancreas
Eating foods containing ………. puts glucose into the blood from the gut
carbohydrate
What removes glucose from the blood normally?
The normal metabolism of cells.
What does vigorous exercise do?
Removes much more glucose from the blood.
How is excess glucose stored?
as glycogen in the liver and muscles
What happens if blood glucose concentration is too high?
The pancreas produces the hormone insulin that causes glucose to move from the blood into the cells. In liver and muscle cells excess glucose is converted to glycogen for storage.
How does insulin control blood glucose levels in the body?
By turning it into glycogen
Type 1 diabetes
- what is it
- How is it treated
- a disorder in which the pancreas fails to produce sufficient insulin. Characterised by uncontrolled high blood glucose levels. Means that blood glucose can rise to a level that kills them.
- insulin therapy- - several injections of insulin throughout the day, usually at mealtimes. Ensures that glucose is removed from blood quickly once food has been digested, stopping levels getting too high
- People with type 1 also need to limit intake of foods rich in simple carbohydrates and take regular exercise.
Type 2 diabetes
-what is it
-risk factor
-treatment
-Body cells don’t respond to insulin produced by the pancreas, so blood sugar level can rise to a dangerous level.
- obesity
- carbohydrate controlled diet and exercise regime
What happens if blood glucose concentration is too low?
The pancreas produces the hormone glucagon that causes glycogen to be converted into glucose and released into the blood.
