CHAPTER 1: THE STUDY OF BODY FUNCTION &
HOMEOSTASIS
,Q1. Physiology is the study of:
A) The structure of the body
B) The function of the body
C) Disease processes
D) The evolution of species
Answer: B) The function of the body ✅
Rationale: Physiology focuses on the function of the body's structures and how they
work together to maintain life, while anatomy is the study of structure.
Q2. The study of how disease or injury alters physiological processes is termed:
A) Comparative physiology
B) The scientific method
C) Pathophysiology
D) Histology
Answer: C) Pathophysiology ✅
Rationale: Pathophysiology deals with disordered function—how disease processes
affect normal physiological function.
Q3. Which of the following best describes negative feedback?
A) A response that amplifies the original stimulus
B) A response that opposes the original deviation from normal
,C) A self-perpetuating cycle leading to an escalating response
D) A mechanism only found in the endocrine system
Answer: B) A response that opposes the original deviation from normal ✅
Rationale: Negative feedback loops are homeostatic mechanisms where the output acts
to reduce or negate the intensity of the original stimulus.
Q4. Blood clotting is an example of positive feedback because:
A) It helps to lower body temperature
B) The action of the effector enhances the stimulus
C) It is controlled by the nervous system
D) It opposes a change in blood pressure
Answer: B) The action of the effector enhances the stimulus ✅
Rationale: In positive feedback, platelets release chemicals that attract more platelets,
accelerating the process until a clot is formed.
Q5. The normal pH range of arterial blood is approximately:
A) 7.00–7.10
B) 7.15–7.25
C) 7.35–7.45
D) 7.50–7.60
Answer: C) 7.35–7.45 ✅
, Rationale: The body maintains a tightly regulated, slightly alkaline pH in arterial blood
between 7.35 and 7.45 for optimal enzyme and cellular function.
Q6. In a homeostatic control system, what is the role of the integrating center?
A) To detect the initial stimulus
B) To send information to the effector
C) To produce the initial change
D) To oppose the effector's action
Answer: B) To send information to the effector ✅
Rationale: The integrating center (e.g., the brain) evaluates sensory input and
determines the appropriate response, then sends a command to the effector.
Q7. What type of homeostatic regulatory mechanisms are the endocrine and nervous
systems considered?
A) Intrinsic mechanisms
B) Autoregulatory mechanisms
C) Extrinsic mechanisms
D) Cellular mechanisms
Answer: C) Extrinsic mechanisms ✅
Rationale: Extrinsic regulation involves control from outside an organ, typically by
nervous and endocrine systems, to coordinate multiple organ systems.
