What is Diabetes?

Diabetes is a disease that affects human body¨s ability to produce or use  insulin which helps transport energy (glucose) from food to cells.

Diabetes Mellitus (Type I)

 - Insulin Dependent
 - body cannot produce insulin

Diabetes (Type II)
 - Non-Insulin Dependent
 - Due to a combination of defective insulin secretion  and defective responsiveness to insulin

Where does insulin come from?


There is only one organ in human body which could secrete insulin-------- It is PANCREAS!


1)Exocrine: Produces digestive enzymes
2)Endocrine: Produce hormones including insulin

　

Normal Pancreas Tissue Structure and Function

 

　

Beta Cells: Secrete Insulin

       All Beta cells are included in islets of pancreas .

Function of Insulin

　

Insulin mediates signal transduction pathway to allow GLUT4 receptor to uptake glucose.
Without Insulin, glucose accumulates in the blood stream leading to toxic effects
