CHAPTER 1 – INTRODUCTION TO A&P
(1–15)
1. The term “anatomy” refers primarily to:
A. Body function
B. Body structure
C. Energy production
D. Chemical regulation
Answer: B
Rationale: Anatomy is the study of body structures, while physiology studies functions.
2. Homeostasis is best defined as:
A. Rapid cellular change
B. Maintaining internal stability
C. Increasing metabolic rate
D. Balancing diet and exercise
Answer: B
Rationale: Homeostasis maintains a stable internal environment despite external changes.
3. The smallest structural and functional unit of life is the:
A. Organ
B. Cell
C. Tissue
D. Molecule
Answer: B
Rationale: The cell is the basic unit capable of carrying out life processes.
4. The body system responsible for long-term regulation through hormones is the:
A. Nervous system
,B. Endocrine system
C. Digestive system
D. Lymphatic system
Answer: B
Rationale: Hormones produced by the endocrine glands regulate long-term body functions.
5. The dorsal cavity contains the:
A. Heart
B. Brain and spinal cord
C. Lungs
D. Liver
Answer: B
Rationale: The dorsal cavity includes the cranial and vertebral cavities.
6. The diaphragm separates which two major cavities?
A. Pelvic and abdominal
B. Dorsal and ventral
C. Thoracic and abdominal
D. Cranial and thoracic
Answer: C
Rationale: The diaphragm divides the thoracic cavity from the abdominopelvic cavity.
7. The anatomical term “superior” means:
A. Closer to the trunk
B. Toward the head
C. Toward the back
D. Farther from the midline
Answer: B
Rationale: Superior means toward the top of the body.
8. In the scientific method, a hypothesis is:
A. A proven theory
B. An educated guess
C. A lab result
D. A statistical test
Answer: B
Rationale: A hypothesis is a tentative explanation needing testing.
9. The ability of the body to sense changes and respond is:
A. Irritability
B. Metabolism
C. Growth
D. Digestion
Answer: A
Rationale: Irritability refers to responsiveness to stimuli.
,10. Blood glucose regulation by insulin is an example of:
A. Positive feedback
B. Negative feedback
C. Passive diffusion
D. Homeostatic failure
Answer: B
Rationale: Negative feedback reverses deviations from normal values.
11. Anatomical position requires:
A. Arms crossed
B. Body prone
C. Palms facing forward
D. Feet together and arms folded
Answer: C
Rationale: Standard position uses forward-facing palms to align joint orientation.
12. The study of tissues is called:
A. Cytology
B. Histology
C. Physiology
D. Pathology
Answer: B
Rationale: Histology examines microscopic tissue structure.
13. A plane dividing the body into right and left sections is the:
A. Coronal
B. Sagittal
C. Transverse
D. Oblique
Answer: B
Rationale: The sagittal plane divides the body vertically into right/left halves.
14. The thoracic cavity contains:
A. Kidneys
B. Heart and lungs
C. Stomach
D. Bladder
Answer: B
Rationale: The thoracic cavity houses the heart and lungs.
15. Physiology describes:
A. Appearance
B. Structure
C. Function
D. Direction
, Answer: C
Rationale: Physiology focuses on how structures work.
CHAPTER 2 – CHEMISTRY OF LIFE
(16–30)
16. The smallest particle of an element is the:
A. Ion
B. Atom
C. Molecule
D. Compound
Answer: B
Rationale: Atoms are the basic chemical units of matter.
17. A positively charged particle is a:
A. Neutron
B. Proton
C. Electron
D. Isotope
Answer: B
Rationale: Protons carry a positive charge.
18. Water is essential because it:
A. Prevents ion formation
B. Is a universal solvent
C. Has no polarity
D. Converts energy
Answer: B
Rationale: Water dissolves substances due to polarity.
