,CHAPTER 1: INTRODUCTION: THEMES IN THE STUDY OF
PHYSIOLOGY
1. Which of the following best describes physiology?
A. The study of how the body structures are formed
B. The study of the functions of the body and its parts
C. The study of diseases and their causes
D. The study of genetics
Answer: B
Rationale: Physiology focuses on how body parts function, while anatomy
studies structure, and pathology studies disease.
2. Homeostasis is best defined as:
A. The body’s ability to produce energy
B. The maintenance of a stable internal environment
C. The growth of tissues in response to stimuli
D. The breakdown of nutrients
Answer: B
Rationale: Homeostasis is the body’s dynamic maintenance of a stable internal
environment, essential for survival.
3. Which of the following is an example of negative feedback?
A. Contractions during childbirth
B. Shivering in response to cold
C. Blood clot formation
D. Lactation
Answer: B
Rationale: Negative feedback counteracts deviations from a set point (e.g.,
shivering generates heat to raise body temperature).
, 4. Positive feedback differs from negative feedback in that it:
A. Promotes stability
B. Enhances a change in the controlled variable
C. Always inhibits a response
D. Maintains homeostasis
Answer: B
Rationale: Positive feedback amplifies a response, such as during labor, rather
than opposing change.
5. Which of the following levels of organization is correct from simplest to
most complex?
A. Organ → Tissue → Cell → Organism
B. Cell → Tissue → Organ → Organ System → Organism
C. Organ → System → Tissue → Cell
D. Tissue → Cell → Organ → System → Organism
Answer: B
Rationale: Cells form tissues → tissues form organs → organs form organ
systems → systems form an organism.
6. Integrative physiology emphasizes:
A. Studying each organ independently
B. Understanding how different systems work together
C. Focusing only on cellular processes
D. Disregarding environmental influences
Answer: B
Rationale: Integrative physiology looks at how organ systems interact to
maintain overall function.
