,1. Multiple Choice: Which of the following structures is
responsible for the exchange of gases in the lungs?
A) Alveoli
B) Bronchi
C) Trachea
D) Diaphragm
Correct Answer: A) Alveoli
Rationale: Alveoli are the tiny air sacs in the lungs where
the exchange of oxygen and carbon dioxide occurs, which
is essential for respiration.
2. Fill-in-the-Blank: The _______ valve prevents backflow of
blood from the aorta into the left ventricle.
Correct Answer: Aortic
Rationale: The aortic valve is crucial for maintaining
unidirectional blood flow during the cardiac cycle.
3. True/False: The kidneys are part of the lower respiratory
tract.
Correct Answer: False
Rationale: The kidneys are organs of the urinary system,
not the respiratory system.
4. Multiple Response: Select all that apply. Which of the
following are functions of the skeletal system?
A) Protection of internal organs
B) Storage of minerals
C) Conduction of sound waves
D) Production of blood cells
Correct Answers: A) Protection of internal organs, B)
Storage of minerals, D) Production of blood cells

, Rationale: The skeletal system protects vital organs,
stores minerals like calcium, and produces blood cells in the
bone marrow. It does not conduct sound waves; that is a
function of the auditory system.
5. Multiple Choice: The primary function of the small
intestine is:
A) Absorption of nutrients
B) Production of digestive enzymes
C) Filtration of waste products
D) Synthesis of vitamins
Correct Answer: A) Absorption of nutrients
Rationale: The small intestine's main role is to absorb
nutrients from digested food into the bloodstream.
6. Fill-in-the-Blank: The basic functional unit of the nervous
system is the _______.
Correct Answer: Neuron
Rationale: Neurons are the cells that transmit nerve
impulses, which are fundamental for nervous system
functions.
7. True/False: Cardiac muscle cells are capable of
spontaneous contraction.
Correct Answer: True
Rationale: Cardiac muscle cells can contract without
neural stimulation due to the presence of pacemaker cells
that regulate the heartbeat.
8. Multiple Response: Which of the following hormones are
secreted by the anterior pituitary gland? Select all that
apply.
A) Growth hormone
