Base your answer on the information below and on your knowledge of biology. Diabetes is a condition characterized by elevated blood sugar levels. One form of diabetes occurs when insulin fails to properly regulate blood sugar levels. Complications from diabetes can include nerve cell damage and poor blood flow, especially in the feet and legs. In individuals with diabetes, wounds usually take longer than normal to heal. One reason for the change in wound healing time in a diabetic is that__________.

Insulin is a peptide hormone made by the pancreas and it regulates how the body uses and stores glucose and fat. It allows the body to use glucose from carbohydrates and breaks down and stores excess glucose as glycogen. Insulin also helps in regulating blood sugar level.

Diabetes causes insulin impairment and defects in the body ability to produce insulin or in its sensitivity to it, and without insulin, the body is unable to manage its sugar level which can lead to high glucose levels.

When the glucose levels become excessively high, it causes impairment in the function of white blood cells which are a key part of the immune system. The impairment of white blood cells results in the inability of the immune system to function correctly, which makes the body less efficient in the fighting off of infections and closing of wounds.
