Remember, Posterior = Pale, P+P

2

What % of the PANCREAS is EXOCRINE tissue?

99%

Where can you find the ISLETS OF LANGERHANS?

In the PANCREAS

Affects - The kidneys ability to remove waste products and extra fluid from the body
AKA: Diabetic Kidney Disease

15

...heart attack

18

What does GLYCATED mean?

that sugar is adhering to proteins

19

Why do diabetics have more GLYCATED HEMOGLOBIN?

It's due to higher levels of GLUCOSE in their BLOOD
