,portage pathophysiology
Which of the following are true of the cell? Select all that apply. - answer✔1: Proteins
carry out the functions of the cell membrane
2:Lysosomes are the digestive system of the cell
3:Microfilaments are thin, threadlike cytoplasmic structures
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
Which are false of the mitochondria? Select all that apply. - answer✔1: They are found
far from the site of energy consumption.
2:They control free radicals.
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
portage pathophysiology
,portage pathophysiology
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
List the 4 types of tissue found in the body. Pick 2 and give a description and example of
each. - 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.
Connective tissue
What term means "cell eating" and engulfs and then kills microorganisms or other
particulate matter? - answer✔Phagocytosis
