Section I: Homeostasis, Organization, and Terminology
(Questions 1–10)
1. Which of the following represents the correct order of structural organization in
the human body, from simplest to most complex?
a) Tissue → Cell → Organ → System → Organism
b) Cell → Tissue → Organ → System → Organism
c) Organ → Tissue → Cell → System → Organism
d) Cell → Organ → Tissue → System → Organism
Rationale: Cells are the basic unit of life; similar cells form tissues; tissues combine to
form organs; organs work together in systems; systems form the organism.
2. Which feedback mechanism is most commonly used to maintain homeostasis?
a) Positive feedback
b) Negative feedback
c) Feed-forward control
d) Homeostatic imbalance
Rationale: Negative feedback reverses a change (e.g., body temperature, blood
glucose), while positive feedback amplifies a process (e.g., childbirth).
,3. The thoracic cavity is separated from the abdominopelvic cavity by the:
a) Mediastinum
b) Diaphragm
c) Pericardium
d) Pleura
Rationale: The diaphragm is a dome-shaped muscle that divides the ventral body
cavity into thoracic and abdominopelvic cavities.
4. Which serous membrane covers the surface of the lungs?
a) Parietal pleura
b) Visceral pleura
c) Visceral pericardium
d) Parietal peritoneum
Rationale: Visceral pleura adheres directly to lung tissue; parietal pleura lines the
thoracic wall.
5. A cut that divides the body into superior and inferior portions is called:
a) Sagittal
b) Frontal
c) Transverse
d) Oblique
Rationale: Transverse (horizontal) plane creates top/bottom sections. Frontal =
anterior/posterior; Sagittal = left/right.
6. The study of tissues is called:
a) Cytology
b) Histology
c) Embryology
d) Pathology
Rationale: Histology = microscopic study of tissues; Cytology = cells.
7. Which directional term means “closer to the point of attachment to the trunk”?
a) Lateral
b) Distal
c) Proximal
d) Superficial
Rationale: Proximal vs. distal – e.g., the elbow is proximal to the wrist.
8. Which organ system is primarily responsible for producing hormones?
a) Nervous system
b) Endocrine system
, c) Lymphatic system
d) Respiratory system
Rationale: Endocrine glands secrete hormones directly into blood.
9. The maintenance of a stable internal environment despite external changes is
known as:
a) Metabolism
b) Homeostasis
c) Adaptation
d) Anabolism
Rationale: Homeostasis = dynamic equilibrium.
10. Which is an example of positive feedback in the body?
a) Regulation of blood pressure
b) Blood clotting cascade
c) Temperature regulation
d) Blood glucose control
Rationale: Blood clotting (platelet activation amplifies until clot forms) and childbirth
(oxytocin release increases contractions) are classic positive feedback loops.
Section II: Chemistry of Life & Cell Structure (Questions 11–25)
11. Which organelle is responsible for ATP production?
a) Ribosome
b) Mitochondrion
c) Golgi apparatus
d) Lysosome
Rationale: Mitochondria perform cellular respiration (Krebs cycle & ETC) to produce
ATP.
12. The cytoskeletal elements that form the mitotic spindle are:
a) Microfilaments
b) Intermediate filaments
c) Microtubules
d) Centrioles
Rationale: Microtubules (made of tubulin) form spindle fibers; centrioles organize
them.
