,Section 1: Organization of the Body
1. Which of the following represents the correct order of structural organization from
simplest to most complex?
a) Tissue → cell → organ → system → organism
b) Cell → organ → tissue → system → organism
c) Cell → tissue → organ → system → organism
d) Organ → tissue → cell → system → organism
Answer: c) Cell → tissue → organ → system → organism
Rationale: The human body is organized hierarchically. Cells are the basic living units; similar
cells form tissues; different tissues work together to form organs; organs with related
functions form systems; all systems integrate to form the organism.
2. Which term refers to the maintenance of a stable internal environment despite external
changes?
a) Metabolism
b) Homeostasis
c) Anabolism
d) Catabolism
Answer: b) Homeostasis
Rationale: Homeostasis is the dynamic equilibrium of the internal environment (e.g.,
temperature, pH, blood glucose). Metabolism refers to all chemical reactions; anabolism and
catabolism are subsets of metabolism.
3. A sagittal plane divides the body into:
a) Superior and inferior portions
b) Anterior and posterior portions
c) Right and left portions
d) Proximal and distal portions
Answer: c) Right and left portions
Rationale: A sagittal plane runs vertically from front to back, separating the body into right
and left sides. A midsagittal plane creates equal halves; a parasagittal plane creates unequal
halves.
4. Which body cavity contains the lungs and heart?
a) Cranial cavity
b) Abdominal cavity
c) Thoracic cavity
d) Pelvic cavity
,Answer: c) Thoracic cavity
Rationale: The thoracic cavity (chest) is subdivided into the pleural cavities (lungs) and the
mediastinum (heart, trachea, esophagus). The cranial cavity houses the brain; the abdominal
cavity contains digestive organs; the pelvic cavity contains reproductive and excretory
organs.
5. The term “medial” means:
a) Toward the back of the body
b) Away from the midline
c) Toward the midline
d) Closer to the point of attachment
Answer: c) Toward the midline
Rationale: Medial indicates a position closer to the body’s midline (e.g., the nose is medial to
the eyes). Lateral is away from the midline; posterior is toward the back; proximal is closer to
the trunk.
6. Which of the following is an example of a negative feedback mechanism?
a) Blood clotting cascade
b) Uterine contractions during childbirth
c) Regulation of blood glucose by insulin
d) Depolarization of a neuron
Answer: c) Regulation of blood glucose by insulin
Rationale: Negative feedback reverses a change (high blood glucose → insulin release →
glucose decreases). Positive feedback amplifies a change (clotting, childbirth, action
potential).
7. Which directional term is opposite of “superficial”?
a) Deep
b) Distal
c) Ventral
d) Superior
Answer: a) Deep
Rationale: Superficial means near the surface; deep means farther from the surface
(internal). Distal refers to distance from trunk; ventral = anterior; superior = above.
8. The abdominopelvic region located in the upper right, just below the ribs, is the:
a) Epigastric region
b) Right hypochondriac region
c) Right iliac region
d) Lumbar region
, Answer: b) Right hypochondriac region
Rationale: The nine-region scheme: hypochondriac (upper lateral), lumbar (middle lateral),
iliac (lower lateral). The epigastric region is upper middle; the right iliac is lower right.
9. Which organ system is primarily responsible for producing body movement and
generating heat?
a) Skeletal system
b) Nervous system
c) Muscular system
d) Endocrine system
Answer: c) Muscular system
Rationale: Muscles contract to produce movement, maintain posture, and generate heat
(thermogenesis). The skeletal system provides leverage; nervous and endocrine systems
regulate muscles but do not produce movement directly.
10. The dorsal body cavity includes the:
a) Thoracic and abdominopelvic cavities
b) Cranial and spinal cavities
c) Pleural and pericardial cavities
d) Abdominal and pelvic cavities
Answer: b) Cranial and spinal cavities
Rationale: The dorsal cavity (posterior) contains the cranial cavity (brain) and
vertebral/spinal cavity (spinal cord). The ventral cavity contains thoracic and abdominopelvic
cavities.
11. Which of the following is a life process that involves the breakdown of complex
substances into simpler ones?
a) Anabolism
b) Catabolism
c) Synthesis
d) Excretion
Answer: b) Catabolism
Rationale: Catabolism is the breakdown phase of metabolism (e.g., digestion, cellular
respiration). Anabolism builds complex molecules; synthesis is a type of anabolism; excretion
removes wastes.
12. The position described as “lying face down” is:
a) Supine
b) Prone
