2. What vessels carry deoxygenated blood away from pulmonary veins
heart?
3. The _ valve lies between right atrium and right ventri- tricuspid
cle
4. The aortic semilunar valve prevents blood from re- left ventricle
turning to the _
5. Layer of heart that serves as dual purpose of lining visceral pericardium (epi-
in the pericardium and forming the outermost wall of cardium)
the heart
6. Heart valves that are not actively closed by the con- semilunar valves
traction of muscular structures
7. The _ has the thickest myocardium because it pumps left ventricle, systemic cir-
blood to the _ cuit
8. Freshly oxygenated blood enters the heart through left atrium, aorta
the _ and is pumped out the _
9. When do the AV valves close during the cardiac cycle? when ventricular pressure
exceeds that of the atria
10. The bicuspid valve is _ located on the left side of
the heart
11. The left side of the heart is responsible for pumping _ oxygenated blood to the
body
12. right ventricle

The pulmonary semilunar valve prevents a back-flow
of blood into the _
13. cardiac output - measurement of the
heart's mechanical efficien-
cy
- amount of blood the heart
pumps in 1 min
- LV
- SV varies with sympathetic
stimulation and venous re-
turn eg. increased venous
return leads to increased
force of contraction
14. Stroke volume - amountt of blood ejected
from hear in one contrac-
tion
15. Ischemia when blood flow is reduced
in a part of the body
16. What would affect SV? preload, afterload (w), con-
tractility
17. Cardiac output formula HR X SV
18. The last in the cardiac conduction sequence is the _ Purkinje fibers
19. the heart contract twice for every heartbeat. one con- pulmonary and aortic veins
traction is the atrial contraction while the other is
the ventricular contraction. during ventricular con-
traction, which two valves of the heart open?
