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.
Metabolism is affected by diabetes. The metabolism of people with diabetes differs to the metabolism of people without it. In type 2 diabetes, the effectiveness of insulin is reduced and in type 1 diabetes, insulin levels in the body are very low. For this reason, type 1 diabetics require insulin delivery from other methods.
