72 times each minute for your entire life
The right ventricle pumps blood to the
Lungs
The upper flat portion of the heart and is located at the level of the second rib
The base

Aortic

Precordium
The lower more pointed end of the heart
Apex
The left heart pumps blood to the
Aorta
SA node is located
Upper posterior wall of the right atrium

Pulmonary circulation
Four chambers of the heart
Two atria and two ventricles
Thin outer most layer of the heart
Epicardium
SA node is referred to as
ectopic
The thickest of the three layers
Myocardium
Delivers oxygenated blood to the myocardium
Coronary arteries
The AV valve located between the left atrium and left ventricle
Bicuspid
Slinglike structures that supports the heart
Pericardium
The large blood vessels attached to the heart is called
Great vessels
This valve is located in the left heart and has chordae tendineae
Bicuspid
Conduction system of the heart
AV node
Bundle of his
Bundle branches right and left
Purkinje fibers
The heart innermost layer
Endocardium
P wave
Atrial contraction (depolarization)
T wave
Ventricle relaxing (repolarization)
Left 5th intercostal
Mitral
QRS
