1. What is anatomy primarily concerned with?
A. Body functions
B. Body structures
C. Disease treatment
D. Drug actions
Correct Answer: B. Body structures
Rationale: Anatomy is the scientific study of body structures and their relationships.
2. What is physiology primarily concerned with?
A. Body structure
B. Body function
C. Body regions
D. Medical terminology
Correct Answer: B. Body function
Rationale: Physiology explains how body structures function and work together to maintain life.
3. Which branch of anatomy studies structures visible without a microscope?
A. Microscopic anatomy
B. Gross anatomy
C. Cytology
D. Histology
Correct Answer: B. Gross anatomy
Rationale: Gross, or macroscopic, anatomy examines structures that can generally be seen
without magnification.
4. Which branch studies tissues?
A. Cytology
B. Histology
C. Embryology
D. Pathology
Correct Answer: B. Histology
Rationale: Histology is the study of tissues, while cytology focuses on cells.
,5. Which branch of microscopic anatomy studies cells?
A. Histology
B. Cytology
C. Regional anatomy
D. Systemic anatomy
Correct Answer: B. Cytology
Rationale: Cytology is the study of individual cells and their structures.
6. Which statement best describes the relationship between anatomy and physiology?
A. They are completely unrelated
B. Structure and function are closely related
C. Anatomy studies only disease
D. Physiology studies only bones
Correct Answer: B. Structure and function are closely related
Rationale: A structure's form helps determine how it performs its function.
7. What is the smallest independently functioning unit of the human body?
A. Tissue
B. Organ
C. Cell
D. Organ system
Correct Answer: C. Cell
Rationale: The cell is the basic structural and functional unit of the human organism.
8. Which is the correct order of structural organization from simplest to most complex?
A. Cell → chemical → tissue → organ → system → organism
B. Chemical → cell → tissue → organ → organ system → organism
C. Tissue → cell → organ → system → organism
D. Chemical → tissue → cell → organ → organism
Correct Answer: B. Chemical → cell → tissue → organ → organ system → organism
Rationale: A&P identifies six major organizational levels: chemical, cellular, tissue, organ, organ-
system, and organismal.
9. Several similar cells working together form a:
A. Tissue
B. System
C. Organ
D. Cavity
,Correct Answer: A. Tissue
Rationale: Cells with similar structures and functions organize into tissues.
10. Two or more tissue types working together form a:
A. Cell
B. Molecule
C. Organ
D. Organism
Correct Answer: C. Organ
Rationale: An organ contains multiple tissue types that work together to perform a specific
function.
11. Which is an example of an organ?
A. Epithelial tissue
B. Heart
C. Neuron
D. Blood
Correct Answer: B. Heart
Rationale: The heart contains several tissue types organized to pump blood.
12. Which level consists of multiple organs working together?
A. Cellular level
B. Tissue level
C. Organ-system level
D. Chemical level
Correct Answer: C. Organ-system level
Rationale: Organ systems consist of organs that cooperate to perform major physiological
functions.
13. Which term describes the body's ability to maintain relatively stable internal conditions?
A. Metabolism
B. Homeostasis
C. Differentiation
D. Growth
Correct Answer: B. Homeostasis
Rationale: Homeostasis maintains internal conditions within a relatively stable range.
14. Which is an example of negative feedback?
A. Labor contractions becoming stronger
, B. Blood glucose regulation
C. Platelet aggregation
D. Blood clotting amplification
Correct Answer: B. Blood glucose regulation
Rationale: Negative feedback counteracts a change and helps return a variable toward its
normal range.
15. Which process is an example of positive feedback?
A. Regulation of body temperature
B. Blood glucose control
C. Childbirth contractions
D. Regulation of blood pressure
Correct Answer: C. Childbirth contractions
Rationale: During labor, contractions stimulate processes that increase contraction strength,
making childbirth a classic positive-feedback example.
16. In a homeostatic control system, what detects a change in a variable?
A. Effector
B. Receptor/sensor
C. Control center only
D. Organ system
Correct Answer: B. Receptor/sensor
Rationale: Receptors detect changes and send information toward the control center.
17. Which component compares incoming information with a desired value and determines
an appropriate response?
A. Receptor
B. Control center
C. Effector
D. Stimulus
Correct Answer: B. Control center
Rationale: The control center evaluates information and directs an appropriate response.
18. Which component carries out the response to a homeostatic signal?
A. Effector
B. Receptor
C. Stimulus
D. Set point
