Physiology, Section 1-2: Anatomy and Physiology Are
Closely Integrated
Stem: A physician explains why the alveoli in the lungs
have extremely thin walls during a respiratory exam. The
student asks why structure matters so much in this organ.
Which statement best explains the relationship being
discussed?
Options:
A. The lungs are thin-walled because all organs must be
fragile to function properly.
, B. The thin walls increase the surface area for gas
exchange and support rapid diffusion.
C. The lungs are thin-walled only to reduce their weight in
the thorax.
D. The alveoli are thin-walled because physiology
determines anatomy only after birth.
Correct Answer: B
Rationale:
Correct Answer: Thin alveolar walls reduce the diffusion
distance between air and blood, which improves gas
exchange. This is a classic example of structure supporting
function.
A: Fragility is not the goal; the structure is specialized for
exchange, not weakness.
C: Weight reduction is not the primary functional reason
for the thin walls.
D: Anatomy and physiology influence each other
throughout life, not only after birth.
Teaching Point: Structure is adapted to function in every
organ system.

• Reference: Unit 1 — Section 1-2
Stem: A biopsy report describes “organized layers of
,epithelial cells with underlying connective tissue.” The
clinician uses this information to explain how the tissue
protects the body surface. Which concept is being applied?
Options:
A. Gross anatomy
B. Microscopic anatomy
C. Regional anatomy
D. Developmental anatomy
Correct Answer: B
Rationale:
Correct Answer: A biopsy reveals structures seen at the
tissue level, which is microscopic anatomy. The function of
the tissue is understood by linking the cell layers to
protection.
A: Gross anatomy deals with structures visible without
magnification.
C: Regional anatomy focuses on body regions, not tissue-
level histology.
D: Developmental anatomy studies structural changes
from conception onward.
Teaching Point: Microscopic structure explains many
tissue functions.

, • Reference: Unit 1 — Section 1-3: Levels of Organization
Progress from Chemicals to a Complete Organism
Stem: During a lab review, a student traces how oxygen
contributes to life processes. The instructor asks for the
correct order from simplest to most complex. Which
sequence is correct?
Options:
A. Cell → atom → tissue → organ → organ system
B. Atom → molecule → cell → tissue → organ → organ
system → organism
C. Molecule → atom → tissue → cell → organ → organism
D. Tissue → cell → organ → molecule → organism
Correct Answer: B
Rationale:
Correct Answer: The human body is organized from
atoms to molecules, then cells, tissues, organs, organ
systems, and the organism. Each level builds on the one
below it.
A: The order is incorrect because atoms come before
cells.
C: Atoms do not follow molecules, and cells come before
tissues.
D: This sequence reverses several levels of organization.
Teaching Point: Biological organization is hierarchical
from chemical to organism level.
