Parts of the Heart
These parts of the heart are an open space for blood to be kept or moved; there are four of them
Which circuit of the heart contains deoxygenated blood?
Pulmonary circuit
This condition occurs when the resting heart rate is below 60 bpm
Bradycardia
Combining form: heart
cardi/o
Combining form: atrium
atri/o
What are the four chambers of the heart called?
Left atrium, right atrium, left ventricle, right ventricle
In this state of the heart, the atrioventricular valve slams shut, and the ventricles eject blood simultaneously
Systole
This type of uncontrollable heart rhythm is a medical emergency and life threatening
Ventrical fibrillation, V-fib, or VF
Suffix: disease
-pathy
Combining form: blood vessel
angi/o
What are the four valves called?
Tricuspid, bicuspid/mitral, pulmonary semil-lunar valve, aortic semi-lunar valve
This state of the heart is relaxed and filled with blood; the atrioventricular valve opens to allow blood flow from the atria to the ventricles
Diastole
This life threatening condition occurs when there is a lack of oxygen to any region of the heart, killing cardiac muscle cells
Myocardial infarction or heart attack
Suffix: producing, originating, causing
-genic
Suffix: stopping or controlling
-stasis
What type of valves are the tricuspid and bicuspid/mitral?
Atrioventricular valve
What is the order of the pulmonary circuit?
Right atrium -> tricuspid valve -> right ventricle -> pulmonary semi-lunar valve -> pulmonary arteries -> lungs -> pulmonary veins
This genetic condition causes an irregular heartbeat rhythm
Arrhythnogenic cardiomyopathy
-megaly
coagul/o
What are the dividers between the atria and ventricles called?
Interatrial septum and interventricular septum
What is the order of the systemic circuit?
Left atrium -> bicuspid/mitral valve -> left ventricle -> aortic semi-lunar valve -> aorta -> body -> superior/inferior vena cava
Patent foramen ovale
Combining form: yellowish, fatty
arther/o
Suffix: formation, production
-poiesis
