CCMA COMPREHENSIVE EXAMINATION
TEST 2026 COMPLETE QUESTIONS AND
CORRECT ANSWERS
◉pericardium. Answer: protective sac enclosing the heart composed
of two layers with fluid between
◉Right atrium. Answer: The upper right chamber of the heart,
where deoxygenated blood is received from the vena cava and then
sent to the right ventricle.
◉Right ventricle. Answer: the chamber on the right side of the heart
that receives deoxygenated blood from the right atrium and pumps
it into the pulmonary trunk
◉Left atrium. Answer: the left upper chamber of the heart that
receives oxygenated blood returning from the lungs via the right and
left pulmonary veins.
◉Left ventricle. Answer: the chamber on the left side of the heart
that receives oxygenated blood from the left atrium and pumps it
into the aorta
,◉Aorta. Answer: The largest artery of the body
◉Pulmonary arteries. Answer: The only arteries in the body that
carry deoxygenated blood.
◉pulmonary veins. Answer: the only veins in the body that carry
oxygenated blood.
◉atrioventricular valves. Answer: Separate the atria and the
ventricles. Right sided tricuspid, left sided mitral
◉tricuspid valve. Answer: between right atrium and right ventricle
◉mitral valve. Answer: between left atrium and left ventricle.
◉Pulmonary valve. Answer: between right ventricle and pulmonary
trunk.
◉Aortic Valve. Answer: Between left ventricle and aorta
◉depolarization. Answer: sodium rushes into neuron through
membrane, potassium ruses out; results in a positive charge
, ◉repolarization. Answer: when the K+ ions leave the inside of the
axon, making the inside charge negative. Myocardial relaxation.
◉SA NODE. Answer: the pace-maker of the heart; where the impulse
conduction of the heart usually starts; located in the top of the right
atrium just below superior vena cava
◉AV node. Answer: Located at the posterior septal wall at the right
atrium just above the tricuspid valve. There is a 1/10 second delay
of electrical activity at this level to allow blood to flow from the atria
to the ventricles.
◉Lead I. Answer: Left arm is positive and right arm is negative (LA-
RA)
◉Lead II. Answer: Left leg is positive and right arm is negative (LL-
RA)
◉Lead III. Answer: Left leg is positive and left arm is negative (LL-
LA)
◉aVR. Answer: The right arm is positive and the other limbs are
negative
