\(y=\frac{1}{x}\) 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 first thing to understand is that wounds heal in four stages. The phases of wound healing are: 1) Hemostasis-clotting and stabilizing of the wound with fibrin and platelets. 2) Inflammation-lasts up to four days. Redness, swelling and warmth occur as white blood cells arrive and prepare to fight infection.
