membrane
2:Lysosomes are the digestive system of the cell
3:Microfilaments are thin, threadlike cytoplasmic structures

hypertrophy is an increase in the size of an organ or tissue caused by an
increase in the number of cells - ✔✔ANSWER✔✔->>>>>>>>True


Which are true of the cell membrane? Select all that apply. - ✔✔ANSWER✔✔-
>>>>>>>>1: Controls the transport of materials from the outside fluids to within
2:Helps with the conduction of electrical currents in nerve and muscle cells
3: Aids in the regulation of cell growth and proliferation

High blood pressure is an example of which of the following? -
✔✔ANSWER✔✔->>>>>>>>pathophysiology


A patient complains of chest pain and an elevated blood pressure. What are
these examples of? - ✔✔ANSWER✔✔->>>>>>>>signs and symptoms


Which of the following is true of a test's sensitivity? - ✔✔ANSWER✔✔-
>>>>>>>>If negative, it can safely be assumed that the person does not have a
disease


Chemical agents (poison, alcohol) are examples of which of the following? -
✔✔ANSWER✔✔->>>>>>>>Etiologic factors


Define tertiary prevention and give an example: - ✔✔ANSWER✔✔-
>>>>>>>>Tertiary prevention occurs after a disease has been diagnosed and
clinical intervention is needed to reduce complications or deterioration. One
example is the use of certain medications one must take after a heart attack to
help reduce the risk of a future event or death.


Compare and contrast the two types of gangrenous necrosis. -
✔✔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. - ✔✔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


sunburn - ✔✔ANSWER✔✔->>>>>>>>radiation injury


obesity - ✔✔ANSWER✔✔->>>>>>>>nutritional imbalances


reactive oxygen species - ✔✔ANSWER✔✔->>>>>>>>free radical injury


low oxygen to tissues - ✔✔ANSWER✔✔->>>>>>>>hypoxic cell injury


fractures - ✔✔ANSWER✔✔->>>>>>>>physical agents


OTC drugs - ✔✔ANSWER✔✔->>>>>>>>Chemical injury


hypothermia - ✔✔ANSWER✔✔->>>>>>>>physical agents


radiation treatment - ✔✔ANSWER✔✔->>>>>>>>radiation injury


lead toxicity - ✔✔ANSWER✔✔->>>>>>>>chemical injury


bacteria - ✔✔ANSWER✔✔->>>>>>>>biologic agents
