1) Anatomy and Physiology Are Integrated
Reference: Chapter 1 — Introduction to Anatomy and
Physiology, Section 1-2
Stem: A patient with emphysema has destruction of alveolar
walls, which greatly reduces the surface area available for gas
exchange. On imaging, the lungs may still appear present and
properly located, but the patient struggles to oxygenate blood
effectively. Which statement best explains this situation?
Options:
A. Anatomy is normal, so physiology must also be normal.
, B. A microscopic structural change can disrupt a major
physiologic process.
C. Gross anatomy is more important than microscopic anatomy
in all cases.
D. Physiology can be understood without considering
structure.
Correct Answer: B
Rationale:
B is correct. The alveoli are microscopic structures whose
shape and surface area are essential for gas exchange. This
shows how structure and function are tightly linked.
A is incorrect. Normal gross appearance does not guarantee
normal microscopic structure or function.
C is incorrect. Microscopic anatomy is often crucial for
understanding organ performance.
D is incorrect. Physiology depends on anatomical structure at
every level.
Teaching Point: Structure determines function from the
microscopic level upward.

2) Gross Anatomy vs. Microscopic Anatomy
,Reference: Chapter 1 — Introduction to Anatomy and
Physiology, Section 1-2
Stem: A surgeon reviews a CT scan before removing a diseased
gallbladder. The scan helps identify the organ’s size and
position, while a tissue biopsy would be needed to evaluate
cell-level damage. Which pairing is correct?
Options:
A. CT scan = microscopic anatomy; biopsy = gross anatomy
B. CT scan = gross anatomy; biopsy = microscopic anatomy
C. CT scan = physiology; biopsy = anatomical position
D. CT scan = sectional physiology; biopsy = regional anatomy
Correct Answer: B
Rationale:
B is correct. Gross anatomy examines structures visible
without magnification, while microscopic anatomy studies
structures seen with a microscope. A CT scan helps with gross
structural assessment, and a biopsy provides microscopic
detail.
A is incorrect. The terms are reversed.
C is incorrect. Neither test directly measures physiology in this
context.
D is incorrect. These labels do not match the methods
described.
, Teaching Point: Imaging often shows gross anatomy; biopsy
reveals microscopic anatomy.

3) Anatomy vs. Physiology in Disease
Reference: Chapter 1 — Introduction to Anatomy and
Physiology, Section 1-2
Stem: A patient has a kidney that appears normal in size and
shape on ultrasound, but laboratory tests show a severe loss of
filtering ability. The provider explains that the organ’s function
is failing even though its visible structure seems preserved.
What is the best interpretation?
Options:
A. Anatomical normality guarantees physiologic normality.
B. Function can be impaired even when gross structure
appears normal.
C. Physiology is independent of organs.
D. Microscopic structure never influences function.
Correct Answer: B
Rationale:
B is correct. Organ function may fail because of cellular or
membrane-level defects that are not obvious on gross imaging.
