Cards

Term
What makes the Pancreas an Exocrine Gland?
Definition
Releases digestive enzymes
Term
What makes the Pancrease an Endocrine Gland?
Definition
Beta cells in the Islets of Langerhans produce and secrete insulin in response to rise in blood sugar
Term
Does insulin ever go down to zero?
Definition
No.  Insulin responde to blood sugars
Term
Name 3 ways that glucose gets into the blood;
Definition

2.  Liver

3.  Protein Catabolism

Term
How does glucose get into blood through Intestine?
Definition
absorption of simple sugars
Term
How does glucose enter blood through liver?
Definition
Convert Glycogen-->Glucose
Term
What is Glycogenolysis?

Term
What is Renal Threshhold?  What happens during renal threshold?
Definition

When BS>200

Body starts to excrete glucose in urine (called Glucoseria)

Term
What does Insulin Do?
Definition

1.  Transport & metabolizes glucose for E

2.  Stimulates storage of glucose in the liver in the form of Glycogen (process called Glycogenesis)
