Question 5
pts
Compare and contrast the two types of gangrenous necrosis.
Your Answer:
Dry gangrene is when the tissue becomes dyhydrated and shrinks back and becomes
dark brown/black in color and the spread of dry gangrene is slow. In wet gangrene the
affected area is cold, swollen, and does not have a pulse, the skin is moist, black and
disteneded. Small blisters blebs on the skins surface where liquefaction occurs and bad
order that is caused by bacteria and the spread of tissue damage is fast.
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.
