CORRECT DETAILED ANSWERS
VERIFIED ANSWERS ALREADY
GRADED A+
What is pathophysiology - Correct Answer: the study of disease processes that alter normal
human physiology
What is disease - Correct Answer: the interruption, cessation, or disorder in the function of a
body
Definition of Etiological factor - Correct Answer: Disease causing factor or agent. Basically the
agent that triggers the disease process
What are examples of a etiologic factor: - Correct Answer: Biological (virus or bacteria),
Physical ( trauma, burns) and Chemicals (poison, alcohol)
Pathogenesis - Correct Answer: cellular and tissue responses to an etiological agent (prior to
onset of disease)
What is an objective sign? (clinical manifestation) - Correct Answer: swelling, fever, difficulty
breathing, pain
what is a subjective symptom?
(clinical manifestation) - Correct Answer: numbness, tingling, malaise
, What is a syndrome? - Correct Answer: compilation of signs and symptoms that are indicative of
a specific disease process.
What is a diagnosis - Correct Answer: Designation of a cause to a disease process
idiopathic - Correct Answer: unknown cause
What are cells - Correct Answer: The smallest functional unit that organisms are divided into and
are necessary to life bc of what they carry inside
what are the functions of cells - Correct Answer: movement, conductivity, metabolic absorption,
secretion, excretion, respiration, reproduction, communication
what is the cell membrane and what it does - Correct Answer: it encloses the cell, provides
intra/extra cellular communication, transports materials,
and maintains activity that powers cell function
What are key parts of the cell membrane? - Correct Answer: it contains a plasma membrane,
phospholipids, glycolipids, cholesterol, carbs, and proteins. they are also hydrophilic and
hydrophobic.
what can harm the plasma membrane? - Correct Answer: free radicals (subs with free electrons
on a o2 molec), high pressure forces (hyper tension) , radiation (sunlight), high glucose
concentrations (diabetes).
what are free radicals - Correct Answer: reactive molecules present in the environment and
generated by the body during ineffecient mitochondrial metabolism. (free e- to an o2 atom)
The body fights free radicals or super oxide molecules with what natural scavenger? - Correct
Answer: antioxidants
