,CHAPTER 1: An Introduction to the Human Body

PART I: MULTIPLE CHOICE (Q1–Q25)

Question 1: What is anatomy?
A) The scientific study of the body's structures
B) The scientific study of the body's functions
C) The study of disease
D) The study of cells
ANS: A
Rationale: Anatomy is the scientific study of the body's structures.

Question 2: What is physiology?
A) The scientific study of the body's functions
B) The scientific study of the body's structures
C) The study of tissues
D) The study of organs
ANS: A
Rationale: Physiology is the scientific study of the body's functions.

Question 3: What is homeostasis?
A) The maintenance of a stable internal environment
B) The disruption of internal environment
C) The study of body structures
D) The study of body functions
ANS: A
Rationale: Homeostasis is the ability to maintain a relatively stable internal state that persists despite
changes in the external environment .

Question 4: Which of the following is the correct order of structural organization from simplest to most
complex?
A) Chemical, cellular, tissue, organ, organ system, organism
B) Organism, organ system, organ, tissue, cellular, chemical
C) Cellular, chemical, tissue, organ, organism, organ system
D) Tissue, cellular, chemical, organ, organ system, organism
ANS: A
Rationale: The body is organized from chemical to cellular to tissue to organ to organ system to
organism .

Question 5: What is the basic functional unit of the human body?
A) Cell
B) Tissue
C) Organ
D) Atom
ANS: A
Rationale: The cell is the basic functional unit of the human body .

,Question 6: What is an organ?
A) A discrete structure made up of two or more tissue types
B) A group of cells working together
C) A group of organs working together
D) The smallest unit of matter
ANS: A
Rationale: Organs are discrete structures made up of two or more tissue types .

Question 7: What is an organ system?
A) A group of organs that work together for common functions
B) A group of cells working together
C) A discrete structure made up of tissues
D) The smallest unit of matter
ANS: A
Rationale: Organ systems are groups of organs that work together for common functions .

Question 8: What is metabolism?
A) The sum of all chemical reactions in the body
B) The study of body structures
C) The maintenance of a stable internal environment
D) The study of body functions
ANS: A
Rationale: Metabolism is the total of changes that a body goes through in its life, including anabolism
and catabolism .

Question 9: What is catabolism?
A) The breakdown of complex compounds into simpler ones, releasing energy
B) The building of complex molecules from simpler ones, requiring energy
C) The maintenance of a stable internal environment
D) The study of body structures
ANS: A
Rationale: Catabolism is the breakdown of complex compounds into simpler ones and tends to release
energy .

Question 10: What is anabolism?
A) The building of complex molecules from simpler ones, requiring energy
B) The breakdown of complex compounds into simpler ones, releasing energy
C) The maintenance of a stable internal environment
D) The study of body functions
ANS: A
Rationale: Anabolism is the chemical reactions that build complex molecules from simpler ones and
require energy .

Question 11: What is a negative feedback mechanism?
A) A mechanism that maintains normal parameters of physiological function inside the body
B) A mechanism that intensifies a physiological change
C) A mechanism that has no effect on physiological function

, D) A mechanism that randomly affects physiological function
ANS: A
Rationale: Negative feedback is a mechanism that maintains normal parameters of physiological
function inside the body .

Question 12: What is a positive feedback mechanism?
A) A mechanism that intensifies a physiological change rather than reversing it
B) A mechanism that maintains normal parameters of physiological function
C) A mechanism that has no effect on physiological function
D) A mechanism that randomly affects physiological function
ANS: A
Rationale: Positive feedback intensifies a physiological change rather than reversing it .

Question 13: What is anatomical position?
A) The body standing upright, feet pointing forward, palms facing the front
B) The body lying face up
C) The body lying face down
D) The body sitting upright
ANS: A
Rationale: Anatomical position is a standardized way to view the human body with the body standing
upright, feet pointing forward, and palms facing the front .

Question 14: What does prone mean?
A) The body is lying face down
B) The body is lying face up
C) The body is standing upright
D) The body is sitting upright
ANS: A
Rationale: Prone describes a face-down orientation .

Question 15: What does supine mean?
A) The body is lying face up
B) The body is lying face down
C) The body is standing upright
D) The body is sitting upright
ANS: A
Rationale: Supine describes a face-up orientation .

Question 16: What does anterior mean?
A) Toward the front of the body
B) Toward the back of the body
C) Toward the midline of the body
D) Away from the midline of the body
ANS: A
Rationale: Anterior (or ventral) means toward the front .
