8. The left side of the heart pumps the same volume as the right.
Pathway of Blood: 10
True or False:
The left side of the heart pumps the same volume as the right.
TRUE

9. L.V. pumps blood with greater pressure.
Pathway of Blood: 20
Why is the left ventricular wall thicker than the right wall of the heart?
L.V. pumps blood with greater pressure.

10. Blood flows where after being pumped out of the right ventricle?
Pathway of Blood: 30

Heart Valves: 20
Prevents backflow into the left atrium
Mitral (bicuspid) vlave

15. FALSE – they both have chordae tendinae
Heart Valves: 30
TRUE or FALSE:
The bicuspid valve has chordae tendinae but the tricuspid valve does not.
FALSE – they both have chordae tendinae

16. Trabeculae carne are found in the ventricles and not in the atria.

TRUE or FALSE:
Trabeculae carne are found in the ventricles and not in the atria.
TRUE

17. Double
Jeopardy!!

18. Heart Valves: 50
The AV valves are supported by these structures so they do not blow back up into the atria during ventricular contraction.
Chordae tendineae

Cardiac Muscle only

21. Properties of Cardiac Muscle: 30
Why is the heart a functional syncytium?
