1. Which of the following represents the correct order of
structural organization from simplest to most complex?
A. Cell → tissue → organ → organ system → organism
B. Tissue → cell → organ → organ system → organism
C. Organ → tissue → cell → organ system → organism
D. Cell → organ → tissue → organ system → organism
Rationale: The correct hierarchy is: chemical level → cellular
level → tissue level → organ level → organ system level →
organismal level. Cells combine to form tissues, tissues form

organs, organs form organ systems, and organ systems work
together to form an organism.
2. The study of the structure of body parts and their relationships
to one another is called:
A. Physiology
B. Histology
C. Anatomy
D. Cytology
Rationale: Anatomy is the study of structure. Physiology (A) is the
study of function. Histology (B) is the study of tissues. Cytology
(D) is the study of cells.
3. Which of the following is an example of a negative feedback
mechanism?
,Page 3 of 118
A. Blood clotting cascade
B. Labor contractions during childbirth
C. Regulation of blood glucose by insulin and glucagon
D. Action potential generation in neurons
Rationale: Negative feedback reverses a change to maintain
homeostasis. Blood glucose regulation: high glucose → insulin
release → glucose uptake → glucose decreases → insulin
decreases. Positive feedback (A, B, D) amplifies a change
(clotting, labor, action potentials).
4. The thoracic cavity is separated from the abdominopelvic
cavity by the:
A. Diaphragm
B. Mediastinum
C. Pleura
D. Peritoneum
, Page 4 of 118
Rationale: The diaphragm is a dome-shaped skeletal muscle that
separates the thoracic cavity (heart, lungs, esophagus) from the
abdominopelvic cavity (stomach, intestines, liver, etc.). The
mediastinum (B) is within the thoracic cavity; pleura (C) lines the
thoracic cavity; peritoneum (D) lines the abdominopelvic cavity.
5. A patient is lying face down on the examination table. This
position is called:
A. Supine
B. Prone
C. Lateral recumbent
D. Trendelenburg
Rationale: Prone = face down. Supine (A) = face up. Lateral
recumbent (C) = lying on side. Trendelenburg (D) = supine with
feet elevated.
