Which are true of the cell membrane? Select all that apply.
,Correct!
Controls the transport of materials from the
outside fluids to within The main structural
component is made of proteins Correct!
, Helps with the conduction of electrical currents in
nerve and muscle cells Correct!
Aids in the regulation of cell growth
and proliferation Question 5
pts
Compare and contrast the two types of
gangrenous necrosis. Your Answer:
Dry gangrene occurs when blood supply is slowly reduced to an area.
The area is dehydrated and becomes dark or black in color. Commonly
seen in patients with diabetes. It is not very painful, but tissues
eventually die.
Wet gangrene is casued with a sudden reduction in blood flow. The area
is cold and swollen, with no pulse. This can occur from trauma.
Bacteria is involved and is very painful. It has the appearance of pus,
becasue it looks wet. There is also a foul smell.
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.
Question 6
