Hole's Human Anatomy and Physiology
SECTION 1: INTRODUCTION TO HUMAN ANATOMY AND PHYSIOLOGY (Questions 1–30)
1. The branch of science that deals with the structure of human body parts is called:
A. Physiology
B. Anatomy
C. Histology
D. Cytology
Rationale: Anatomy is the study of the structure of body parts and their relationships to one
another. Physiology is the study of function, histology is the study of tissues, and cytology is the
study of cells.
2. An investigator who conducts an experiment to determine how temperature changes affect
the rate at which the heart beats is most likely a(n):
A. Anatomist
B. Physiologist
1|Page
,Page 2 of 70
C. Chemist
D. Biochemist
Rationale: Physiology deals with the functions of body parts—what they do and how they do it.
Studying how temperature affects heart rate is a functional question, making this a physiological
investigation.
3. The term "anatomy" is derived from Greek words meaning:
A. To study function
B. To cut apart
C. To examine tissues
D. To study cells
Rationale: The term "anatomy" comes from the Greek words ana (up) and tome (cutting),
meaning "to cut apart" or "to dissect." This reflects the historical practice of dissecting cadavers
to observe internal structures.
4. Which of the following examples represents a positive feedback mechanism in the human
body?
A. Regulation of body temperature via sweating
B. Control of blood glucose levels by insulin
C. Uterine contractions during childbirth
D. Maintenance of blood pressure by heart rate adjustments
Rationale: Positive feedback mechanisms amplify or reinforce a change away from the body's
normal baseline, such as oxytocin increasing uterine contractions during labor. The other
choices represent negative feedback.
5. The biological level of organization that stands directly between the organ level and the
cellular level is the:
A. Chemical level
B. Organ system level
2|Page
,Page 3 of 70
C. Tissue level
D. Organism level
Rationale: The hierarchy of biological organization proceeds from chemical, cellular, tissue,
organ, organ system, to organism. Tissues consist of groups of similar cells working together to
perform a specialized function.
6. The mediastinum is a sub-region located within which major body cavity?
A. Pelvic cavity
B. Abdominal cavity
C. Vertebral canal
D. Thoracic cavity
Rationale: The thoracic cavity contains the left and right pleural cavities (housing the lungs) and
the central mediastinum, which houses the heart, thymus, esophagus, and trachea.
7. A surgical incision that divides the body into superior and inferior portions is known as a:
A. Sagittal plane
B. Transverse plane
C. Coronal plane
D. Frontal plane
Rationale: A transverse (or horizontal) plane cuts horizontally, separating the body into top
(superior) and bottom (inferior) sections. Sagittal cuts separate left from right, and
coronal/frontal cuts separate front from back.
8. Which type of chemical bond is formed when electrons are completely transferred from
one atom to another?
A. Nonpolar covalent bond
B. Polar covalent bond
C. Ionic bond
D. Hydrogen bond
3|Page
, Page 4 of 70
Rationale: Ionic bonds form due to the electrostatic attraction between oppositely charged ions
created when electrons are transferred. Covalent bonds involve sharing electrons, while
hydrogen bonds are weak attractions between polar molecules.
9. A solution with a pH of 3.0 has ______ times more hydrogen ions (H⁺) than a solution with
a pH of 6.0.
A. 3
B. 100
C. 1,000
D. 10,000
Rationale: The pH scale is logarithmic. A difference of 3 pH units corresponds to a 10³ = 1,000-
fold difference in H⁺ concentration.
10. The study of the function of body parts is called:
A. Anatomy
B. Physiology
C. Histology
D. Cytology
Rationale: Physiology is the study of the functions of body parts—what they do and how they
do it.
11. Which of the following is NOT a characteristic of life?
A. Movement
B. Responsiveness
C. Metabolism
D. Immortality
Rationale: Characteristics of life include movement, responsiveness, metabolism, growth,
reproduction, and organization. Immortality is not a characteristic of living organisms.
12. The term "homeostasis" refers to:
