Compare and contrast the two types of gangrenous necrosis. Correct Answer: 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. Correct Answer:
necrosis is cell death to an organ or tissue with still being apart of a living person. An example of this
would be luiquefactive necrosis. this is when the cells die and the catalytic enzymes do not get
destroyed after the cells death. This could cause necrosis

List the 4 types of tissue found in the body. Pick 2 and give a description and example of each. Correct
Answer: Epithelial tissue- covers the body's outer surface, it is avascular and gets its o2 from the
capillaries found in the neighboring connective tissues, and example of this is simple squamous tissue
which means one layer of thin cells.
Muscular tissue
Nervous tissue- is found all throughout the body, helps with communication between tissues and the
central nervous system. it aids in the functions of the body due to internal and external stimuli, helps
, with movement, and electrical signaling. neurons are an example of this, they aid in communicating to
other cells in the body, they are held and supported by glial cells.
