SECTION I — INTRODUCTION
Questions 1–40
,1. What is anatomy?
A. The study of body function
B. The study of body structure
C. The study of disease only
D. The study of chemical reactions
Correct answer: B
Rationale: Anatomy focuses on the structures of the body and the relationships among those
structures. Physiology, in contrast, focuses on how those structures function.
2. What is physiology?
A. The study of body structure
B. The study of tissues only
C. The study of how body structures function
D. The study of anatomical terminology
Correct answer: C
Rationale: Physiology examines the functions and mechanisms of living organisms. Structure
and function are closely related because anatomical characteristics frequently determine
physiological capabilities.
3. Which level of organization consists of atoms and molecules?
A. Cellular
B. Tissue
C. Chemical
D. Organ
Correct answer: C
Rationale: The chemical level is the simplest level of structural organization. Atoms combine to
form molecules, which participate in the chemical processes necessary for life.
4. Which sequence correctly represents increasing structural complexity?
A. Organ → tissue → cell → chemical
B. Chemical → cellular → tissue → organ → organ system
,C. Tissue → chemical → organ → cell
D. Cellular → chemical → organ → tissue
Correct answer: B
Rationale: Human organization progresses from chemical components to cells, tissues, organs,
and organ systems, ultimately forming the organism.
5. Which is an example of an organ?
A. Epithelial tissue
B. A neuron
C. The heart
D. A protein molecule
Correct answer: C
Rationale: An organ contains at least two tissue types working together to perform specific
functions. The heart contains muscle, connective, epithelial, and nervous tissues.
6. Which organ system is primarily responsible for transporting oxygen, nutrients,
hormones, and wastes?
A. Cardiovascular
B. Skeletal
C. Integumentary
D. Nervous
Correct answer: A
Rationale: The cardiovascular system circulates blood throughout the body, allowing substances
to move between tissues and organs.
7. What does homeostasis mean?
A. Complete absence of physiological change
B. Maintenance of relatively stable internal conditions
C. Elimination of all disease
D. Continuous increase in body temperature
Correct answer: B
, Rationale: Homeostasis maintains internal variables within a physiological range. It does not
mean that conditions remain absolutely constant.
8. Which mechanism generally counteracts a deviation from a normal value?
A. Positive feedback
B. Negative feedback
C. Feedforward inhibition
D. Structural feedback
Correct answer: B
Rationale: Negative feedback opposes the initial change and helps restore a variable toward its
normal range. Temperature regulation is a classic example.
9. Which is an example of positive feedback?
A. Regulation of body temperature
B. Blood glucose regulation
C. Labor contractions during childbirth
D. Regulation of blood calcium
Correct answer: C
Rationale: During labor, uterine contractions promote cervical stretching, which increases
signals that intensify contractions. This amplifies the original stimulus.
10. In anatomical position, the palms face:
A. Posteriorly
B. Medially
C. Anteriorly
D. Inferiorly
Correct answer: C
Rationale: Anatomical position places the body standing upright, facing forward, with arms at
the sides and palms facing forward.
11. The term “superior” means:
