with correct answers
What is the purpose of the inflammatory process? (p. 191) Correct
Answer-If he epithelial barrier is damaged, a highly efficient local and
systemic response, inflammation, is mobilized to limit the extent of
damage, protect against infection, and initiate repair of the damaged
tissue. Inflammation associated with infection usually initiates an
adaptive process that results in a long-term and very effective immunity
to the infecting micro-organism, referred to as adaptive, acquired, or
specific immunity.
What is the blood type of a person who is heterozygous, having A and B
alleles as codominant? Correct Answer-...He will have AB blood type
How do surfactant proteins A and D provide innate protection? Correct
Answer-...The promote phagocytosis
What is the cause of familial hypercholesterolemia (FH)? (p. 173)
Correct Answer-FH is most commonly caused by a reduction in the
number of functional LDL receptors on cell surfaces. Lacking the
normal number of LDL receptors, cellular cholesterol uptake is reduced
and circulating cholesterol levels increase.
Which cancers cluster strongly in families? Correct Answer-...Breast and
colon cancers cluster strongly in families
, Which genes are responsible for an autosomal dominant form of breast
cancer? Correct Answer-...BRCA1 and BRCA2
What is a characteristic of atopic individuals who are genetically
prodisposed to develop allergies? Correct Answer-...They produce
greater quantities of IgE than other individuals
What activates the complement system? (p. 197) Correct Answer-The
complement system consists of several plasma proteins that are
sometimes called the complement components, that together constitute
about 10% of the total circulating serum protein. The complement
system is extremely important because activation of the complement
cascade may destroy pathogens directly and can activate or collaborate
with virtually every other component of the inflammatory response
Proteins of the complement system are among the body's most potent
defenders, particularly against bacterial infection. Activation of the
complement system can be accomplished in 3 different pathways, all of
which converge at the third component (C3) of the pathway:
1) Classical pathway: activated by proteins of the adaptive immune
system, antibodies, bound to their specific targets or antigens
2) Lectin pathway: activated by mannose-containing bacterial
carbohydrates
3) Alternative pathway: activeated by gram-negative bacterial and
fungal cell wall polysaccharides.
Activation of C1 initiates the sequential enzymatic activation of all other
components of the classical pathway, ultimately resulting in the
activation of C5. The classical pathway also can be activated to a lesser
degree by biologic molecules other than antibody, including heparin or
