Biology 5.2.3 Flashcards
Which Gland in the Human Endocrine System Monitors & Controls Blood Glucose Concentration?
The Pancreas.
Blood ___ Concentration is an example of ___. Why?
Homeostasis. Because it must be Maintained/Regulated.
When the Blood Glucose Concentration is too High, the Pancreas will Secrete the Hormone ___ to bring it back down.
Insulin.
How does Insulin help in Regulating Blood Glucose Concentration when it is too High?
Insulin Stimulates Cells to take in Glucose from the Bloodstream. (Particularly the Liver & Muscles Cells).
What happens to Excess Glucose in the Liver & Muscle Cells?
It is Converted into Glycogen for Efficient Storage.
What is ‘Type 1 Diabetes’?
A Disorder in which the Pancreas fails to Produce sufficient Insulin to Control Blood Glucose Levels.
How do People get Type 1 Diabetes?
Born with it.
How is Type 1 Diabetes Treated?
With Insulin Injections.
What is ‘Type 2 Diabetes’?
When the Body Cells no longer Respond to Insulin Produced by the Pancreas. Insulin is still Produced, but the Cells are Resistant.
What can be done to Treat Type 2 Diabetes?
Maintaining a Low-Carbohydrate Diet, & Regular Exercise, to Reduce the need for Insulin.
If the Blood Glucose Concentration is too Low, the Pancreas Produces the Hormone ___.
Glucagon.
When the Blood Glucose Concentration is too Low, Glucagon is Secreted from the Pancreas. What does it do?
Glucagon causes Glycogen to be Converted into Glucose, & Released into the Blood.
Glucagon & Insulin Interact as part of a ___ ___ Cycle to Control Blood Glucose Levels in the Body.
Negative Feedback.
___ is Produced in the Pancreas when Blood Glucose Rises.
Insulin.
___ is Produced in the Pancreas when Blood Glucose Lowers.
Glucagon.
