1. The use of non-invasive and painless
Echocardiology
ultra- sound to examine the heart, its
chambers and valves is known as:
2. Waveforms may be displayed on a
screen called an: Electrocardiogram
3. The breastbone is referred to as: sternum
4. The pericardial sac that surrounds the heart: Has a tough fibrous outer
layer called
the visceral pericardium and an
inner, thin transparent lining
called the fi- brous pericardium
5. What are the 3 layers of the heart wall? Epicardium, myocardium,
endocardi-
um
6. The atrioventricular valve between the Mitral valve
left atrium and the left ventricle is
the:
Interatrial septum
7. The wall that separates the two
superior chambers of the heart is
called:
8. The heart valves that separates the atria from Atrioventricular valves
the ventricles are called that:
9. The skeleton of the heart: Separates the atria from the
ventricles

are influenced by the brain via the
nervous system.
12. The cardioaccelerator center: Is part of the sympathetic nervous
sys- tem
13. The most muscular chamber of the heart that Left ventricle
forces blood through the aortic valve
into the aorta would be the:
14. During depolarization: Impulses are generated and
transmit- ted when positively
charged ions move inside the cell
causing the interior to become
positively charged
15. Blood returns to the heart from the Pulmonary veins
lungs via four blood vessels called:
16. Blood travels to the lungs where carbon diox- Pulmonary arteries
ide is unloaded and oxygen is loaded.
The blood vessels that carry the blood
from the heart to the lungs are:
17. During which phase of the cardiac cycle do the Early systole
coronary arteries fill?
18. How much of the blood coming into the 80%
ven- tricles flows passively through
the atria?

up a larger box, represent 0.20
seconds in duration
