described.
Q13: The central nervous system consists of the
ISSA Certification Final Exam • Comprehensive Practice • 2026/2027 Page 2
, A. Brain and spinal cord [CORRECT]
B. Cranial nerves and spinal nerves only
C. Heart and lungs
D. Endocrine glands only
Correct Answer: A
Rationale: The brain and spinal cord form the CNS; peripheral nerves and endocrine glands are separate systems.
Q14: What is the functional role of a motor unit?
A. One motor neuron and all the muscle fibers it innervates [CORRECT]
B. One bone and the ligament around it
C. One tendon and one joint capsule
D. One sensory receptor and one gland
Correct Answer: A
Rationale: A motor unit is a motor neuron plus its innervated muscle fibers and is the basic unit of neural control of
skeletal muscle.
Q15: A client struggles to stabilize the trunk during a deadlift. Which system primarily coordinates motor-unit
recruitment and movement control?
A. The nervous system [CORRECT]
B. The digestive system
C. The integumentary system
D. The lymphatic system only
Correct Answer: A
Rationale: The nervous system plans and coordinates movement and recruitment; the other systems do not primarily
control voluntary motor actions.
Q16: Which chamber pumps oxygenated blood into systemic circulation?
A. Left ventricle [CORRECT]
B. Right ventricle
C. Right atrium
D. Left atrium only
Correct Answer: A
Rationale: The left ventricle ejects oxygenated blood through the aorta; the right ventricle pumps to the lungs and the
atria receive blood.
Q17: What is the normal direction of blood flow through the pulmonary circuit?
A. Right ventricle to pulmonary arteries to lungs to pulmonary veins to left atrium [CORRECT]
B. Left ventricle to vena cava to lungs
C. Right atrium directly to aorta
D. Left atrium to pulmonary arteries to body
Correct Answer: A
Rationale: The right ventricle sends deoxygenated blood to the lungs and pulmonary veins return oxygenated blood to
the left atrium; the other pathways are incorrect.
Q18: During systole, the ventricles primarily
A. Contract and eject blood [CORRECT]
B. Relax and fill only
C. Exchange gases in the alveoli
D. Filter metabolic waste
Correct Answer: A
Rationale: Ventricular systole is contraction and ejection; filling occurs primarily during diastole and gas exchange or
filtration occur elsewhere.
Q19: A client’s heart rate is 150 beats/min during intense exercise. Which immediate cardiovascular response is
expected?
A. Increased cardiac output to support working muscles [CORRECT]
