NHA Certified EKG Tech
Mediastenum Correct Answer: space where heart is located, just behind the sterum

The top of the heart location Correct Answer: second intercostal

Base of the heart location Correct Answer: 5th intercostal and mid clavicular line on the left

Endocardium Correct Answer: The innermost layer of the heart

chordae tendinae Correct Answer: connective tissue that keep the AV valves in place

Heart skeleton Correct Answer: Pericardium, parietal pericardium, visceral pericardium or epicardum
and pericardial sac

Parietal pericardium Correct Answer: outside layer of the heart skeleton

Visceral pericardium or epicardium Correct Answer: the inner layer of the heart

Pericardial Sac Correct Answer: The layers and fluid between the two layers of the pericardium that
prevent friction

septum Correct Answer: A wall of tissue that separates the left and right sides of the heart, The septum
prevents oxygen rich and oxygen poor blood from mixing in the heart.

Right side of the heart Correct Answer: Pumps deoxygenated blood with low pressure from veins to the
lungs; responsible for pulmonary circulation

Left side of the heart Correct Answer: Pumps oxygenated blood with high pressure toward the tissue
through the arteries; responsible for systemic circulation

Number of chambers in the heart Correct Answer: four

Right and left atria Correct Answer: Smaller, thin walled chambers that are situated on top of the
ventricles and receive blood from the lungs and veins

Right and left ventricles Correct Answer: Larger, more muscular chambers that eject blood to the
systemic circulation and the two lungs

Right atrium RA Correct Answer: Receives deoxygenated blood returning to the heart from the body via
the superior and inferior vena cava

Coronary Sinus Correct Answer: The largest vein that drains the heart muscle's deoxygenated blood
received by the RA

, Right Ventricle RV Correct Answer: Receives deoxygenated blood from the RA which is pumped to the
lungs for oxygenation through the pulmonary trunk and the pulmonary arteries

Pulmonary arteries PA Correct Answer: The only arteries that carry deoxygenated blood

Pulmonary valves >PA> Pulmonary trunk> lungs>PV> LA> bicuspid or MV> LV> SL LV> systemic aortic
valve

Heart valves Correct Answer: Prevents the back flow of blood ensuring uni-directional flow through the
heart

Atrio-ventricular valves Correct Answer: Valves between the atria and ventricles that are have tough

Tricuspids valves Correct Answer: located between the right atria and right ventricle, it has three cusp

Bicuspids / mitral valves Correct Answer: located between the left atria and ventricle, two cusp

Pulmonic valve Correct Answer: located between the left ventricle and the pulmonary trunk

Aortic Valve Correct Answer: located between the left ventricle and the aorta

coronary arteries Correct Answer: located on the epicardium

Four vessels in coronary circulation Correct Answer: Left Anterior Descending (LAD), Left Circumflex
(LCX) artery and the Left and Right Coronary

Systole Correct Answer: Contraction of both atrial and ventricles

diastole Correct Answer: Relaxation and filling of all cardiac chambers

Heart Sounds Correct Answer: Closure of the heart valves

S1 (Lubb) Correct Answer: During ventricular contraction and closure of AV valves

S2 (Dubb) Correct Answer: During ventricular relaxation when SL valves closes

Heart murmurs Correct Answer: Disease of the valves or any other abnormalities
