\(y=\frac{1}{x}\) 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.
Infected wounds are wounds in which bacteria or other microorganisms have colonized, causing either a delay in wound healing or deterioration of the wound. Most wounds are typically contaminated by bacteria. However, infected wounds result when the body's immune defenses are overwhelmed or cannot cope with normal bacterial growth.
