Chapter 18: The Heart
Cardiac muscle tissue is found in which layer of the heart
Myocardium
This valve is found between the right atrium and the right ventricle
Tricuspid
which blood vessles leave the heart and transport blood to the lungs?
Pulmonary arteries
These structures prevent prolapse of the atrioventricular valves
Chordae tendineae
All of these structures can be identified in the ventricles EXCEPT
Pectinate Muscles
Blood is carried tot he heart by these vessels
Veins
what is the definition of arteries
Carry blood away from the heart
Blood being pumped out of the left ventricle enters the
Aorta
Blood is prevented from flowing back into the left ventricle by the
Aortic semilunar valve
Deoxygenated blood from the myocardium enters the right atrium through the
Coronary sinus
Without SA node input, what would the heart rate be
50 beats per minute
The bundle of his is located here
Interventricular septum
Artial repolarization occurs during this period of time, seen on an ECG
QRS complex
The entire ventricular myocardium remains depolarized during this time on an ECG
S-T segment
