Chapter/Section: Chapter 1, Section 1.1
An Overview of Anatomy & Physiology
Subtopic: Complementarity of Structure & Function
Cognitive Level: Recall
Difficulty: Easy
Stem: Which statement best expresses the principle of
complementarity of structure and function?
A. Function is independent of structure.
B. Structure determines function; change the structure and
function changes.
C. Function determines structure; changes in function change
structure immediately.
D. Anatomy studies cells only; physiology studies organs only.
Correct answer: B
Rationale (correct): Marieb emphasizes that anatomical
structure determines physiological function — e.g., the shape of
bones and joint surfaces enables movement and load-bearing;
altering structure alters function. This principle underlies
organization across scales in the textbook. Pearson
Why A is wrong: It contradicts the central textbook principle —
function depends on structure, not independent of it.
,Why C is wrong: While function can influence structure over
time (adaptation), the textbook states the general rule is that
structure determines function, not the reverse as a rule.
Why D is wrong: Both anatomy and physiology study all levels
(cells → organs), not exclusively as stated.
Teaching Point: Structure (anatomy) enables and constrains
function (physiology).

Chapter 1, Section 1.2; Marieb 12th Ed., Ch.1, levels of
structural organization (pages in sample).
Subtopic: Levels of Organization (atoms → organism)
Cognitive Level: Recall
Difficulty: Easy
Stem: Which sequence correctly orders the levels of structural
organization from smallest to largest?
A. Molecule → Atom → Organ → Tissue → Organism
B. Atom → Molecule → Cell → Tissue → Organ → Organ System
→ Organism
C. Cell → Atom → Molecule → Tissue → Organ
D. Tissue → Cell → Organ → System → Molecule
Correct answer: B
Rationale (correct): Marieb lists the hierarchical organization:
chemical (atoms → molecules), cellular, tissue, organ, organ
,system, organism. This hierarchy frames how small-scale
properties affect whole-body function. Pearson
Why A is wrong: Atom precedes molecule; sequence is
incorrect.
Why C is wrong: Atom and molecule cannot come after cell —
they are chemical building blocks.
Why D is wrong: Order is scrambled; molecules are smallest.
Teaching Point: Body organization builds from chemical to
organism level in a fixed hierarchy.

Chapter 1, Section 1.3; Marieb 12th Ed., Necessary Life
Functions (Fig.1.3).
Subtopic: Necessary Life Functions — Maintaining Boundaries
Cognitive Level: Application
Difficulty: Medium
Stem: A patient with severe burns has extensive loss of skin.
Which life function is most directly threatened?
A. Reproduction
B. Maintaining boundaries
C. Movement
D. Metabolism
Correct answer: B
Rationale (correct): The integument (skin) maintains internal-
external boundaries; Marieb notes boundary maintenance
, protects internal tissues and prevents fluid loss and pathogen
entry. Severe burns impair this function, increasing dehydration
and infection risk. Pearson Canada School+1
Why A is wrong: Reproduction is not immediately compromised
by skin barrier loss.
Why C is wrong: Although mobility can be affected by burns,
the primary immediate threat is loss of boundary and fluid
control.
Why D is wrong: Metabolism may be secondarily affected
(hypermetabolic response), but the direct life function hit is
boundary maintenance.
Teaching Point: Skin protects internal environment — loss of
skin disrupts homeostasis and increases infection/dehydration
risk.
A&P004
Chapter 1, Section 1.3; Marieb 12th Ed., Necessary Life
Functions: Movement.
Subtopic: Movement (internal and external)
Cognitive Level: Recall
Difficulty: Easy
Stem: Which example best illustrates the textbook’s broad
definition of “movement”?
A. Contraction of skeletal muscle to lift a cup.
B. Production of red blood cells in marrow.
