STRUCTURE & FUNCTION
OF THE BODY — 16th EDITION
ORIGINAL EXAM MASTERY • 100 QUESTIONS • 2026 STUDY EDITION
An independently authored anatomy & physiology practice resource inspired by the chapter structure
of Patton & Thibodeau. It is designed to strengthen recall, concept integration, and application rather
than reproduce a commercial test bank.
Coverage All 22 chapters of the 16th-edition structure
Format 100 original multiple-choice questions with answers and rationales
Emphasis Anatomy, physiology, homeostasis, structure-function relationships, and clinical application
Study method Attempt → commit to an answer → review rationale → explain the concept in your own words
Originality notice: The questions, options, answers, rationales, review material, and memory aids in this PDF were newly authored. No locked or
paid Stuvia content or proprietary test-bank questions have been reproduced.

, Study Strategy
1. Start with relationships, not isolated facts. Connect structure to function: alveolar surface area → diffusion;
nephron segments → urine concentration; membrane composition → transport.
2. Use the rationale as the lesson. If you miss a question, explain why each distractor is wrong rather than
memorizing the correct letter.
3. Use the homeostasis framework. Identify the variable, sensor, control center, effector, and response whenever a
physiology question describes regulation.
4. Watch the wording. 'Primary,' 'most directly,' 'best describes,' and 'greatest immediate risk' often signal the level of
specificity being tested.
High-Yield Concepts
Concept Core idea
Homeostasis A dynamic steady state maintained by coordinated feedback mechanisms.
Negative feedback Counteracts a deviation and tends to restore a variable toward its set range.
Positive feedback Amplifies a process until a defined endpoint occurs.
Structure → function Cell/tissue architecture constrains what the structure can do.
Membrane transport Diffusion follows gradients; active transport requires energy; osmosis concerns water movement.
Perfusion Blood flow depends on pressure gradients and vascular resistance.
Acid-base Lungs regulate CO2 rapidly; kidneys regulate H+ and bicarbonate more slowly.
Fluid balance Sodium strongly influences extracellular volume; potassium dominates intracellular cation concentration.
Clinical A&P Symptoms often reflect disruption of normal structure-function relationships.

, 1. Introduction to the Body
Question 1. Which sequence correctly represents the major levels of organization from simplest to most complex?
A. Chemical → cellular → tissue → organ → organ system → organism
B. Organ → tissue → cellular → chemical → organism
C. Cellular → chemical → tissue → organ system → organ
D. Tissue → chemical → organ → cellular → organism
Answer: A
Rationale: The body is organized from chemical components to cells, tissues, organs, organ systems, and finally the whole
organism.
Question 2. Which anatomical term means farther from the point of attachment of a limb?
A. Distal
B. Proximal
C. Medial
D. Superior
Answer: A
Rationale: Distal means farther from the point of attachment; proximal means closer.
Question 3. A patient is lying face down. Which position is being described?
A. Prone
B. Supine
C. Fowler
D. Lithotomy
Answer: A
Rationale: Prone means lying face down; supine means lying face up.
Question 4. Which plane divides the body into anterior and posterior portions?
A. Frontal (coronal)
B. Sagittal
C. Transverse
D. Oblique
Answer: A
Rationale: The frontal plane separates anterior from posterior regions.
2. Chemistry of Life
Question 5. Which bond involves sharing electrons between atoms?
A. Covalent
B. Ionic
C. Hydrogen
D. Peptide only
Answer: A
Rationale: Covalent bonds form when atoms share electrons.
