1. 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 .
2. The study of how disease or injury alters physiological
processes is termed:
1
,a) Comparative physiology.
b) The scientific method.
c) Pathophysiology.
d) Histology.
Answer: c) Pathophysiology.
Rationale: Pathophysiology is the specific branch that deals with
disordered function, or how disease processes affect normal
physiological function .
3. 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 that leads to an escalating response.
d) A mechanism that is only found in the endocrine system.
Answer: b) A response that opposes the original deviation
from normal.
Rationale: Negative feedback loops are homeostatic
2
,mechanisms where the output of a system acts to reduce or
negate the intensity of the original stimulus, thereby maintaining
a stable internal environment .
4. 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, the initial stimulus produces a
response that reinforces and amplifies the change. In blood
clotting, platelets release chemicals that attract more platelets,
accelerating the process until a clot is formed .
5. The normal pH range of arterial blood is approximately:
a) 7.00 - 7.10
b) 7.15 - 7.25
3
, 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 the arterial blood between 7.35 and 7.45 for
optimal enzyme and cellular function .
6. 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 the
sensory input and determines the appropriate response, which it
