Introduction to the respiratory system organs: The respiratory system is the system of the human body by which it produces energy needed for life processes. 1  This energy is produced by the breaking down of glucose molecules in all living cells of the human body.
The most susceptible organs and systems effected by diabetes are the eyes, the kidneys, the nerves, the cardiovascular system. The only system I recall not being effected by diabetes is the respiratory system but I can't be 100% on that.
How can diabetes affect my feet? Chronically high blood sugar (glucose) levels can be associated with serious complications in people who have diabetes. The feet are especially at risk. Two conditions called diabetic neuropathy and peripheral vascular disease can damage the feet (and other areas of the body) in people who have diabetes.
