1. The pancreas is a unique organ located behind the , and serves 2 roles
: & production.: stomach
digestion & hormone
2. The majority of the pancreas' function is the / function.: diges-
tive/exocrine
3. 98% of pancreatic cells are cells. These are the main cells involved in the pancreas's function.
What are their role?: acinar Exocrine
-produce digestive enzymes and bicarb, released into GI tract to break down food
4. the pancreas' endocrine function = production
This is a portion of the pancreas' functions, but is responsible for produc- ing important things like
.: hormone
smaller
insulin
5. The of langerhaan make up 1-2% of the pancreatic weight. They provide the
function of the pancreas.
The islets are microscopic cell surrounded by . This aids
hormone release into .
This is important because islet cells secrete hormones directly into the blood without the use of .: islets

6. What are the 4 islet cell types in the pancreatic islets of langerhaans?
If you care to know, what percent of the pancreas do each of them make up?: 1) alpha cells - 25%
2) beta cells - 60%
3) Delta cells - 10%
4) PP cells
7. What two hormones are secreted by beta cells in the pancreas?: - insulin
- amylin
8. Which hormone is secreted by alpha cells in the pancreas?: Glucagon
9. What hormone is secreted by delta cells in the pancreas?
What is the function of this hormone?: 10% somatostatin
Function= suppress insulin and glucagon release
10.What hormone is secreted from PP cells in the pancreas? What is the function of this hormone?:
pancreatic polypeptide
Function = inhibits exocrine secretion from pancreas
11.Insulin and glucagon are important because they help regulate the of
carbohydrates, fats, and proteins.
They are important in regulating how the body responds to intake and
periods of .: Metabolism
Food
Fasting
12.The primary energy source for the body is . The liver functions as a storage center
for glucose in the form of . It is capable of maintaining normal blood sugar for -
hours without eating.

Despite fluctuations in blood glucose from eating and fasting, tightly
regulate blood glucose levels to maintain a normal value.: Glucose

Hormones
13.A normal overnight fasting glucose level is -
After meals, blood glucose levels rise to - before returning to the baseline
level. This is normal.: 80-90
120-140
14.A patient with impaired glucose tolerance is considered , espe-
cially if their fasting plasma glucose level is between - mg/dL
A diabetic patient, the fasting plasma glucose level is typically equal to or greater than mg/dL:
Prediabetic
100-125

15. is the process of storing glucose in the liver and muscle as glycogen.
The breakdown of glycogen into glucose is called .
is the storage of glucose (energy) as fat in adipose tissue. The break- down of these stores is called
.: glycogenesis
glycogenolysis
lipogenesis lipolysis
16.Gluconeogenesis is when glucose is formed from substrates.
