Compare and contrast the two types of gangrenous necrosis.
In dry gangrene the affected tissue becomes dry and shrinks, the skin wrinkles, and its color changes to dark
brown or black. The spread of dry gangrene is slow. It results from a cut off in arterial blood supply and is a
form of coagulation necrosis. In wet gangrene, the affected area is cold, swollen, and pulseless. The skin is
, moist, black, and under tension. Blebs form on the surface, liquefaction occurs, and a foul odor is caused by
bacterial action. The spread of tissue damage is rapid.
Explain what necrosis is and give an example and description of one type of necrosis.
Necrosis is cell death to an organ or tissue with still being a part of a living person. An example of this would
be liquefactive necrosis. This is when the cells die and the catalytic enzymes do not get destroyed after the
cells death. This could cause necrosis
