is
pancreas??

3. pancreas
It is a large gland in body that secrete hormones.
The cells that make up of pancreatic islet.
Also known as “islet of langerhans”
It is part of two different organ system
-Endocrine system
-Digestive system

4. Con’t…
There are 3 main cell in the pancreatic islet :
beta cells, which secrete insulin and amylin
alpa cells, which secrete glucagon
delta cells, which secrete somatostatin

5. LoCation…
Whole a located in the epigastric and left
hypochondriac regions and its right part lies
across the bodies of L1 to L3 vertebrae.
It runs transversely across the posterior
abdominal wall behind the stomach, from the
duodenum to the spleen, sloping upward from
right to left
It is approximately 12.5 – 15cm long and
weighs from 60 – 100gm.

pancreas, (6) inferior surface of pancreas, (7) superior margin
of pancreas, (8) anterior margin of pancreas, (9) inferior

8. Function of Insulin..
Purpose:-Regulate blood glucose (sugar) in
the normal range.
Action:-Forces many cells of the body to
absorb and use glucose thereby decreasing
blood sugar levels.
Secreted in response- High blood glucose
Secretion inhibit by- low blood glucose

9. FunCtion oF GLuCaGon…
Purpose:- Assist insulin in regulating blood
glucose (sugar) in the normal range.
Action: Forces many cells of the body to
release (or produce) glucose (increasing blood
sugar).
Secreted in response to - low blood glucose
Secretion inhibit by - high blood glucose

10. Somatostatin
Purpose:- Regulate the production and
excretion of other endocrine hormones
Action:- produce by hypothalamus to inhibit
insulin, glucagon, gastrin, and other endocrine
hormones
Secreted in response to - High levels of
other endocrine hormones
Secretion inhibit by- Low levels of other
endocrine hormones

11. summary
Responsible for the endocrine function.
It is a large gland in body that secrete
hormones.
Secreted the major hormones in the endocrine
system
