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.
1 Kidney failure can occur. 2  If nerves get affected by diabetes it can lead to tingling, numbness, burning, or, shooting or stabbing pain in the feet, hands, or other parts of the body.  If the nerves that control internal organs are damaged then the person may suffer from sexual and digestive problems.
