EXAM QUESTIONS
QUESTION 1
Body activities such as breathing, circulation, and heartbeat are regulated by the
CORRECT ANSWER
B. Autonomic nervous system
RATIONALE: The autonomic nervous system regulates involuntary functions such as breathing, circulation, and
heartbeat through a complex network of nerves and organs that operate without conscious control. This allows the body
to maintain essential functions even when the individual is not actively thinking about them, ensuring a stable and
consistent internal environment.
QUESTION 2
Which gas is brought into the body, and which is eliminated by the respiratory system?
CORRECT ANSWER
D. Oxygen, carbon dioxide
Trusted by thousands of students and professionals worldwide Page 1 of 49
, RATIONALE: During inhalation, the respiratory system brings oxygen into the body, which is essential for cellular
respiration and energy production. Conversely, during exhalation, the respiratory system eliminates carbon dioxide, a
waste product of cellular respiration, from the body.
QUESTION 3
The muscular tissue of the heart is called the
CORRECT ANSWER
C. Myocardium
RATIONALE: The term "C. Myocardium" is correct because it refers to the specific layer of the heart wall composed of
cardiac muscle cells, which are responsible for the heart's contraction and pumping function. This term is derived from
the Greek words "myo" meaning muscle and "kardia" meaning heart, making it a scientifically accurate and descriptive
term for the heart's muscular tissue.
QUESTION 4
Blood enters the right atrium of the heart from the
CORRECT ANSWER
B. Vena cava
RATIONALE: The superior and inferior vena cava are two large veins that return deoxygenated blood from the body to
the right atrium of the heart, with the superior vena cava being responsible for returning blood from the upper body and
the inferior vena cava from the lower body. Therefore, when considering the origin of blood entering the right atrium,
both veins are relevant, making "B. Vena cava" a correct answer as it encompasses both the superior and inferior vena
cava.
QUESTION 5
The disorder characterized by degeneration of the myelin sheath is
CORRECT ANSWER
A. Multiple sclerosis
RATIONALE: Multiple sclerosis is characterized by the degeneration of the myelin sheath due to the body's immune
system mistakenly attacking and damaging the protective covering of nerve fibers. This damage disrupts communication
between nerve cells, leading to a wide range of symptoms and neurological problems.
QUESTION 6
The functional, microscopic filtration unit of the kidney is the
CORRECT ANSWER
B. Nephron
Trusted by thousands of students and professionals worldwide Page 2 of 49
, RATIONALE: The nephron is considered the functional filtration unit of the kidney because it contains the glomerulus, a
network of capillaries where blood filtration occurs, and the Bowman's capsule, which collects the filtered waste and
excess fluids. This unique structure and function enable the nephron to efficiently filter waste and excess substances
from the blood, making it a crucial component of the kidney's overall filtration process.
QUESTION 7
The testes produce
CORRECT ANSWER
D. Both A and B. A - Sperm; B - Testosterone
RATIONALE: The testes produce sperm, which is a key component of male reproductive cells, and testosterone, a
hormone essential for male development and fertility. These two substances are crucial for the male reproductive system
and play vital roles in reproduction and overall male health, making the testes a unique and complex organ with multiple
functions.
QUESTION 8
The amount of circulating blood in the body of an average adult is about
CORRECT ANSWER
D. 6 liters
RATIONALE: The correct answer is due to the total blood volume in an adult being comprised of the sum of blood in the
circulatory system, which includes the heart, arteries, veins, and capillaries, and the blood within organs such as the
liver, spleen, and lungs that filter and store blood. This volume is estimated to be roughly 7% of the adult's total body
weight, which for an average adult weighing around 70 kilograms (or 154 pounds), is approximately 6 liters.
QUESTION 9
The main function of white blood cells is to
CORRECT ANSWER
B. Defend the body against invading bacteria and viruses
RATIONALE: White blood cells play a crucial role in the immune system by recognizing and neutralizing foreign invaders
such as bacteria and viruses through mechanisms like phagocytosis and the release of chemical signals, thereby
protecting the body from infection and disease. This function is essential for maintaining overall health and preventing
the spread of illnesses, making it a vital aspect of white blood cell function.
QUESTION 10
The process that stops bleeding is called
CORRECT ANSWER
B. Hemostasis
Trusted by thousands of students and professionals worldwide Page 3 of 49
, RATIONALE: Hemostasis is the correct process because it refers to the complex mechanism that involves the activation
of platelets, blood clotting factors, and other cellular processes to form a plug and seal off damaged blood vessels,
thereby stopping bleeding. The term "Hemostasis" comes from the Greek words "haima" meaning blood and "stasis"
meaning standing still, which accurately reflects its function of stopping blood flow.
QUESTION 11
The spinal cavity contains the
CORRECT ANSWER
C. Spinal cord
RATIONALE: The spinal cord is the long, thin, tube-like structure that extends from the base of the brain down to the
lower back, serving as the main pathway for nerve signals between the brain and the rest of the body. Given its location
within the spinal cavity, a narrow, fluid-filled space within the vertebral column, the spinal cord is the only structure that
fits within this specific cavity.
QUESTION 12
Air is brought into the lungs by way of the
CORRECT ANSWER
C. Trachea
RATIONALE: The correct answer "C. Trachea" is due to the trachea acting as the primary airway that connects the throat
to the lungs, allowing air to flow into the respiratory system. This tube, also known as the windpipe, divides into the
bronchi that lead to the lungs, facilitating the inhalation process.
QUESTION 13
The longest and strongest bone of the skeleton is the
CORRECT ANSWER
A. Femur
RATIONALE: The femur is the longest and strongest bone of the skeleton due to its unique structure, which consists of a
thick, dense shaft that provides excellent support and resistance to stress, as well as its robust ball-and-socket joint at
the hip that enables it to bear heavy loads. In comparison to other bones, the femur undergoes minimal stress and strain
due to its position in the lower limb, allowing it to maintain its structural integrity and support the body's weight
effectively.
QUESTION 14
The dome-shaped muscle that separates the thoracic cavity from the abdominal cavity is the
CORRECT ANSWER
C. Diaphragm
