Biology B3 3.7 Controlling blood glucose.

HideShow resource information
What is the level of glucose in the blood controlled by?
Hormones.
1 of 12
Why do blood glucose levels rise in Type 1 diabetes?
Because it is not controlled properly.
2 of 12
What monitors and controls the level of glucose in our blood?
The pancreas.
3 of 12
What does the pancreas do when there is too much glucose in our blood?
Produces the hormone insulin.
4 of 12
What does insulin do?
Causes the glucose to move from the blood into the cells.
5 of 12
What happens to excess glucose in the liver?
It is converted to glycogen for storage.
6 of 12
If no, or too little, insulin is produced by the pancreas the blood glucose level may become very high, what is this condition known as?
Type 1 diabetes.
7 of 12
How is Type 1 diabetes controlled?
By injections of insulin and careful attention to diet and levels of exercise.
8 of 12
What effect does insulin have on blood glucose?
Insulin causes blood glucose levels to fall, particularly after a meal when glucose enters the blood from the intestines.
9 of 12
What does glucagon cause?
Glucagon causes glucogen to change to glucose which goes back into the blood when blood glucose levels are too low.
10 of 12
What happens in the pancreas if the level of blood glucose gets too low?
Receptors in the pancreas detect the low blood glucose levels and the pancreas releases glucagon, which is another hormone.
