| Chapters 1–3 Real Questions & Accurate Answers |
Latest 2026
1. Describe the significance of the B-cell receptor (BCR) complex in the context
of autoimmune disorders.
The BCR complex is responsible for the direct destruction of
pathogens.
The BCR complex is crucial for recognizing antigens, which can lead
to the production of antibodies that may mistakenly target the
body's own tissues in autoimmune disorders.
The BCR complex has no role in autoimmune disorders.
The BCR complex only functions in response to bacterial infections.
2. What is the class of immunoglobulins primarily involved in allergic reactions
such as hay fever?
IgG
IgA
IgE
IgM
3. Type 2 diabetes is best described as a:
Presence of insulin autoantibodies that destroy beta cells in the
pancreas
Increase of glucagon secretion from alpha cells of the pancreas
Heightened muscle sensitivity to insulin
Resistance to insulin by insulin-sensitive tissues
,4. Describe the role of natriuretic peptides in the cardiovascular system.
Natriuretic peptides function to decrease the levels of insulin in the
blood.
Natriuretic peptides help regulate blood pressure and fluid balance
by promoting vasodilation and natriuresis.
Natriuretic peptides are responsible for increasing heart rate and
cardiac output.
Natriuretic peptides primarily stimulate the production of red blood
cells.
5. What structure does the epiphysis merge with after the epiphyseal plate
calcifies?
diaphysis
periosteum
articular cartilage
metaphysis
6. Describe how damage to the plasma membrane can affect mitochondrial
function.
Damage to the plasma membrane enhances mitochondrial energy
efficiency.
Damage to the plasma membrane has no effect on mitochondrial
function.
Damage to the plasma membrane only affects the nucleus, not the
mitochondria.
Damage to the plasma membrane can lead to mitochondrial
dysfunction, resulting in decreased ATP production and impaired
, energy metabolism.
7. What type of pressure increases due to venous obstruction, leading to
edema?
Osmotic pressure
Arterial pressure
Venous pressure
Hydrostatic pressure
8. Which of the following describes the underlying pathology of Graves'
disease?
inflammation of the thyroid gland due to lymphocytic infiltration
causes the stored thyroid hormones to be released into the
circulation, leading to hyperthyroidism
an autoimmune disease directed against TSH receptors, in which the
autoantibodies stimulate TSH receptors and cause increased T3 and
T4 production
a benign tumor of the thyroid gland which produces excessive
amounts of thyroid hormones
9. In a patient with severe pulmonary embolism affecting Zone I of the lung,
what physiological consequence would you expect?
Increased oxygen saturation
Decreased gas exchange efficiency
Enhanced ventilation rates
Improved blood flow to the lungs
, 10. What is one potential effect of plasma membrane damage on mitochondria?
Disruption of ATP production
Improved calcium storage
Enhanced cellular respiration
Increased protein synthesis
11. Natriuretic Peptides (ANP and BNP) have:
vasodilatory properties
diuretic & vasodilatory properties
vasoconstriction properties
diuretic properties
12. In a clinical scenario where a patient is experiencing excessive cell death
due to a disease, how might understanding apoptosis help in treatment
planning?
Understanding apoptosis can help in identifying therapeutic
targets to regulate cell death and promote cell survival.
Understanding apoptosis can only help in predicting the progression
of the disease, not in treatment.
Understanding apoptosis is only relevant for cancer treatments and
not for other diseases.
Understanding apoptosis will not influence treatment planning as it is
unrelated to disease processes.
13. Describe the role of hydrostatic pressure in the movement of water between
plasma and interstitial fluid.
