\(y=\frac{1}{x}\) This means that the line y=0 is a horizontal asymptote. Horizontal asymptotes occur most often when the function is a fraction where the top remains positive, but the bottom goes to infinity. Going back to the previous example, \(y=\frac{1}{x}\) is a fraction.
Causes of Wounds. Wound causes can be internal or external in origin. Wounds of internal origin are mainly due to impaired circulation, neuropathy or medical illness. Wounds of external origin are due to an outside force or trauma that causes open or closed wounds.
The Causes of Wounds Healing Slowly. All wounds heal in three stages. First, the wound becomes inflamed as an immune response to prevent infections. Second, new cellsâbetter known as a scabâform over the wound. And finally scar tissue forms, healing the wound. While cuts with even edges tend to heal quicker and better than cuts than rough edges, disease and nutritional deficits can cause the healing process to slow in both types of wounds.
