SECTION I: INTRODUCTION TO THE HUMAN BODY
Question 1
Type: Multiple Choice
Which branch of science studies the functions of body structures, focusing on how the body
works?
A) Anatomy
B) Histology
C) Physiology
D) Embryology
Correct Answer: C) Physiology
Rationale: Physiology is the scientific study of the functions of body structures, emphasizing
how the body works and the processes that maintain life . Anatomy (A) studies body structures.
Histology (B) is the microscopic study of tissues. Embryology (D) studies development before
birth.
Question 2
Type: Multiple Choice
A group of cells with similar structure and function, along with the extracellular matrix they
secrete, is best defined as a:
A) Molecule
B) Tissue
C) Organ
D) Organ System
Correct Answer: B) Tissue
, Rationale: A tissue is defined as a group of cells with similar structure and function that
work together to perform a specific activity . Molecules (A) are chemical building blocks. Organs
(C) are composed of two or more tissue types. Organ systems (D) consist of related organs with
a common function.
Question 3
Type: Multiple Choice
Which of the following correctly lists the levels of structural organization from simplest to most
complex?
A) Atom → Molecule → Cell → Tissue → Organ → Organ System → Organism
B) Molecule → Atom → Organelle → Cell → Tissue → Organ → Organism
C) Atom → Molecule → Organelle → Cell → Tissue → Organ → Organ System → Organism
D) Cell → Tissue → Organelle → Molecule → Atom → Organ → Organism
Correct Answer: C) Atom → Molecule → Organelle → Cell → Tissue → Organ → Organ
System → Organism
Rationale: The correct hierarchy of structural organization begins with the chemical level
(atoms and molecules), progresses through organelles, cells, tissues, organs, and organ systems,
culminating in the organismal level . Option A omits the organelle level. Option B reverses atom
and molecule. Option D is inverted.
Question 4
Type: Select All That Apply
Which of the following are primary functions of the integumentary system?
A) Protection against environmental hazards
B) Regulation of body temperature
C) Synthesis of vitamin D
D) Production of red blood cells
E) Detection of touch, pressure, and pain
Correct Answers: A, B, C, E
, Rationale: The integumentary system provides protection, regulates temperature,
synthesizes vitamin D, detects cutaneous sensations, excretes wastes, and serves as a blood
reservoir . Red blood cell production (D) is a function of the skeletal system (red bone marrow),
not the integumentary system.
Question 5
Type: Multiple Choice
The fluid that fills the narrow spaces between cells and directly bathes body cells is called:
A) Blood plasma
B) Lymph
C) Interstitial fluid
D) Cerebrospinal fluid
Correct Answer: C) Interstitial fluid
Rationale: Interstitial fluid (also called tissue fluid) fills the microscopic spaces between cells
and tissues, providing nutrients and removing wastes from cells . Blood plasma (A) is the liquid
portion of blood within vessels. Lymph (B) is fluid within lymphatic vessels. Cerebrospinal fluid
(D) surrounds the brain and spinal cord.
Question 6
Type: Multiple Choice
In a feedback system, which component detects changes in a controlled condition and sends
input to the control center?
A) Effector
B) Receptor
C) Control Center
D) Stimulus
Correct Answer: B) Receptor
Rationale: The receptor is the component of a feedback system that monitors the
controlled condition and detects changes (stimuli), sending input to the control center . The
, effector (A) produces the response. The control center (C) processes input and generates
output. The stimulus (D) is the change itself, not the detector.
Question 7
Type: Multiple Choice
Which plane divides the body into equal right and left halves?
A) Frontal (coronal) plane
B) Transverse plane
C) Midsagittal plane
D) Parasagittal plane
Correct Answer: C) Midsagittal plane
Rationale: A midsagittal plane divides the body into equal right and left halves along the
midline . A frontal plane (A) divides into anterior and posterior portions. A transverse plane (B)
divides into superior and inferior portions. A parasagittal plane (D) divides into unequal right
and left portions.
Question 8
Type: Multiple Choice
The term "cranial" refers to which body cavity?
A) The cavity containing the heart and lungs
B) The cavity formed by the skull bones that encases the brain
C) The cavity containing the spinal cord
D) The cavity containing the digestive organs
Correct Answer: B) The cavity formed by the skull bones that encases the brain
Rationale: The cranial cavity is the space formed by the cranial bones of the skull that
contains and protects the brain . The thoracic cavity (A) contains the heart and lungs. The
vertebral (spinal) cavity (C) contains the spinal cord. The abdominal cavity (D) contains digestive
organs.
