Controlling blood glucose levels Flashcards
Which gland produces and secretes insulin?
Insulin is produced and secreted from the pancreas
What is homeostasis?
Homeostasis is the controlling of a constant internal environment.
Why is it important to control homeostasis?
It is important to control homeostasis because our cells wouldn’t function properly if the conditions were too far from normal.
What is thermoregulation?
Thermoregulation is the controlling of body temperatures.
What is Blood glucose regulation?
Blood glucose regulation is the controlling of blood glucose levels.
What is added when the glucose levels are too high?
Insulin is released to the blood when glucose levels are too high.
What does insulin do at the liver and why is it important?
Insulin converts glucose into glycogen so that glycogen is released and the glucose is controlled therefore reducing the amount of blood glucose levels in the blood?
What happens if the blood glucose levels are too low?
Glucagon is released and secreted from the pancreas and realised into the blood.
When the glucagon reaches the liver, it causes the change of glycogen into glucose.
This glucose is then released into the blood and the levels of glucose in the blood increases.
What is a negative feedback system?
a negative feedback system helps to keep your bodies conditions steady by detecting changes and a response counteracts the change causing the change to be reduced and the body conditions return back to normal.
Give an example of a negative feedback system.
rise in blood glucose levels causes a response to lower the blood glucose levels and vice versa.
What effect does eating Carbs have on the blood glucose levels?
eating foods containing carbs puts glucose into the blood from small intestines.
normal metabolism of cells removes glucose from blood
What effects does exercise have on the blood glucose levels?
Exercise removes much more glucose from the blood
How is excess glucose stored?
Excess glucose is stored as lipids which is fats in the tissues.
