1.1 Overview of Anatomy and Physiology
Question 1 An exercise physiologist measures a subject's rate of oxygen consumption (VO2)
and blood lactate accumulation during incremental treadmill testing. This study primarily falls
under which discipline, and why?
A) Gross anatomy, because it examines large systemic cardiovascular pathways.
B) Systemic anatomy, because it isolates specific muscular tissue structures.
C) Pathological physiology, because high lactate levels represent cellular damage.
D) Cardiovascular and exercise physiology, because it measures functional homeostatic
responses of organ systems during physical exertion.
•
Correct Answer: D
• Rationale: Physiology focuses on the dynamic function and operational processes of
body structures, including functional responses to stressors like exercise.
o A is incorrect: Gross anatomy examines structures visible without a microscope,
not dynamic metabolic rates.
o B is incorrect: Systemic anatomy studies structural relationships of an entire
system, not functional metabolic rates.
o C is incorrect: Elevated lactate during intense exercise is a normal physiological
byproduct of anaerobic glycolysis, not necessarily pathological.
• Examiner Tip: Distinguish functional dynamic studies (Physiology) from static
structural observations (Anatomy).
• Reference: OpenStax Anatomy and Physiology 2e, Section 1.1.
Question 2 A surgical resident prepares to perform an appendectomy by reviewing the regional
anatomy of the right lower quadrant. Which statement best distinguishes regional anatomy from
systemic anatomy?
A) Regional anatomy studies all structures within a specific body region simultaneously,
whereas systemic anatomy studies all organs that work together to perform a broad function
regardless of location.
, B) Regional anatomy relies exclusively on microscopic analysis, whereas systemic anatomy uses
gross dissection.
C) Regional anatomy focuses on pathological changes, whereas systemic anatomy focuses only
on healthy developmental structures.
D) Systemic anatomy organizes the body by body cavities, whereas regional anatomy organizes
the body by tissue types.
•
Correct Answer: A
• Rationale: Regional anatomy analyzes all anatomical structures (muscles, nerves, blood
vessels, bone) in a designated spatial area (e.g., abdomen, arm). Systemic anatomy
studies all structures composing an entire functional organ system (e.g., all organs of the
digestive system) throughout the entire body.
o B is incorrect: Both approaches utilize gross anatomical methods.
o C is incorrect: Neither approach is inherently limited to pathology or
developmental biology.
o D is incorrect: Systemic anatomy is organized by organ systems, not body
cavities or tissue types alone.
• Examiner Tip: Look for keywords indicating spatial organization (Regional) versus
functional system grouping (Systemic).
• Reference: OpenStax Anatomy and Physiology 2e, Section 1.1.
1.2 Structural Organization of the Human Body
Question 3 Which sequence correctly orders the levels of structural organization in the human
body from simplest to most complex?
A) Chemical → Cellular → Tissue → Organ → Organ System → Organismal
B) Cellular → Chemical → Tissue → Organ System → Organ → Organismal
C) Tissue → Chemical → Cellular → Organ → Organismal → Organ System
D) Chemical → Tissue → Cellular → Organ System → Organ → Organismal
•
Correct Answer: A
