CERTIFIED MEDICAL ASSISTANT (CMA / CCMA) PRACTICE EXAM 2026
COMPLETE STUDY GUIDE WITH VERIFIED QUESTIONS & DETAILED EXPERT
RATIONALE
• This practice exam contains 200 carefully curated questions covering all core
CMA/CCMA domains — use it by attempting each question independently before
revealing the answer, then study the EXPERT RATIONALE to reinforce your
understanding.
• Features verified answers with detailed EXPERT RATIONALE, bold highlights on
correct options, and full topic coverage including Clinical Procedures, Phlebotomy,
EKG, Pharmacology, Patient Care, Medical Law, Anatomy, and Administrative Skills.
SECTION 1: ANATOMY & PHYSIOLOGY
1. Which chamber of the heart pumps oxygenated blood to the systemic
circulation?
A. Right atrium
B. Right ventricle
C. Left atrium
D. Left ventricle ✓
E. Interventricular septum
, Correct Answer: D. Left ventricle EXPERT RATIONALE: The left ventricle
has the thickest muscular wall of all four chambers because it must generate
enough pressure to pump oxygenated blood through the aorta and into the entire
systemic circulation. The right ventricle pumps deoxygenated blood only to the
lungs via the pulmonary artery.
2. The mitral valve is located between which two structures?
A. Right atrium and right ventricle
B. Right ventricle and pulmonary artery
C. Left ventricle and aorta
D. Left atrium and left ventricle ✓
E. Superior vena cava and right atrium
Correct Answer: D. Left atrium and left ventricle EXPERT RATIONALE:
The mitral (bicuspid) valve has two leaflets and separates the left atrium from the
left ventricle. It prevents backflow of blood into the left atrium during ventricular
contraction. The tricuspid valve serves the same function on the right side of the
heart.
3. Which organ is responsible for producing insulin?
A. Liver
B. Adrenal gland
C. Thyroid gland
D. Pancreas ✓
E. Spleen
Correct Answer: D. Pancreas EXPERT RATIONALE: The beta cells of the
islets of Langerhans in the pancreas produce insulin, which facilitates glucose
,uptake into cells. Alpha cells produce glucagon, which raises blood sugar.
Dysfunction of these beta cells leads to Type 1 diabetes mellitus.
4. The largest artery in the human body is the:
A. Femoral artery
B. Carotid artery
C. Pulmonary artery
D. Aorta ✓
E. Subclavian artery
Correct Answer: D. Aorta EXPERT RATIONALE: The aorta originates from
the left ventricle and is the largest and main artery of the systemic circulation. It has
four segments: ascending aorta, aortic arch, thoracic aorta, and abdominal aorta,
giving off branches that supply all organs and tissues.
5. Which part of the brain controls balance and coordination?
A. Cerebrum
B. Medulla oblongata
C. Hypothalamus
D. Cerebellum ✓
E. Thalamus
Correct Answer: D. Cerebellum EXPERT RATIONALE: The cerebellum,
located in the posterior cranial fossa, coordinates voluntary muscle movements,
maintains posture, and regulates balance. Damage to the cerebellum results in
ataxia — a lack of voluntary coordination of muscle movements.
6. The functional unit of the kidney is called the:
, A. Glomerulus
B. Loop of Henle
C. Collecting duct
D. Nephron ✓
E. Renal pelvis
Correct Answer: D. Nephron EXPERT RATIONALE: The nephron is the
basic structural and functional unit of the kidney. Each kidney contains
approximately one million nephrons. It consists of the glomerulus, Bowman's
capsule, proximal convoluted tubule, loop of Henle, and distal convoluted tubule,
all working together for filtration, reabsorption, and secretion.
7. Which type of muscle tissue is found in the walls of hollow organs such as
the intestines?
A. Cardiac muscle
B. Skeletal muscle
C. Striated muscle
D. Smooth muscle ✓
E. Voluntary muscle
Correct Answer: D. Smooth muscle EXPERT RATIONALE: Smooth muscle
is involuntary and non-striated, found in the walls of hollow organs including the
intestines, bladder, and blood vessels. It contracts under autonomic nervous
system control to move substances through organs via peristalsis or regulate
vascular tone.
8. The hormone responsible for the "fight or flight" response is:
A. Cortisol
B. Aldosterone
