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.
Diabetes can affect many parts of your body, including your nerves. Your body contains a large network of nerves, which carry electric signals to and from your brain. The signals going from your body TO the brain bring information about the outside world.
