UNIT 1: FOUNDATIONS OF PHYSIOLOGY (Questions 1-25)
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
, Page 3 of 77
Rationale: Physiology focuses on how the body's structures work together to maintain life,
whereas anatomy is the study of structure. Understanding physiology involves analyzing
cause-and-effect mechanisms at molecular, cellular, and systemic levels .
2. 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 bridges basic physiology and clinical medicine by examining
how normal physiological processes are disrupted by disease or injury .
3. Negative feedback mechanisms:
A) Tend to move the body away from homeostasis
B) Are exemplified by blood clotting and childbirth
C) Counteract a change from a set point
D) Amplify the initial stimulus
Answer: C) Counteract a change from a set point
Rationale: Negative feedback mechanisms oppose a change from a set point by reducing the
intensity of the initial stimulus. This self-regulating mechanism promotes stability and is the
most common type of feedback in the body (e.g., body temperature regulation, blood glucose
control) .
4. Positive feedback mechanisms:
A) Tend to maintain homeostasis
B) Are exemplified by blood clotting and childbirth
C) Always lead to disease
D) Are more common than negative feedback
Answer: B) Are exemplified by blood clotting and childbirth
Rationale: Positive feedback amplifies a change, moving a system away from its set point
toward an endpoint. In childbirth, oxytocin release intensifies uterine contractions until
delivery. In blood clotting, activated platelets release chemicals that attract more platelets,
, Page 4 of 77
forming a clot. Unlike negative feedback, positive feedback is rarely used in healthy
physiology .
5. The level of organization from simplest to most complex is:
A) Cell, tissue, organ, organ system, organism
B) Tissue, cell, organ, organ system, organism
C) Organ, tissue, cell, organ system, organism
D) Cell, organ, tissue, organ system, organism
Answer: A) Cell, tissue, organ, organ system, organism
Rationale: This hierarchy reflects the structural organization of the human body. Cells (the
basic living units) form tissues, tissues combine to create organs, organs work together in
organ systems, and all systems collectively form the complete organism .
6. The normal range of arterial blood pH is:
A) 6.50-7.00
B) 6.95-7.35
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. Deviations below 7.35
indicate acidosis; deviations above 7.45 indicate alkalosis .
7. What makes a hypothesis scientific?
A) It is an educated guess
B) It is proven to be true
C) It can be tested
D) It is based on a theory
Answer: C) It can be tested
Rationale: For a hypothesis to be scientific, it must be falsifiable and testable through
experimentation or observation. It does not need to be initially true, but it must be able to be
proven false by reproducible data .
8. Extracellular fluid (ECF) includes which of the following?
