  1. Ch. 18 • Heart Anatomy • JEOPARDY!

  2. Final Jeopardy

  3. Coverings, Layers & Chambers : 10 • The inner lining of the heart? • Endocardium

  4. Coverings, Layers & Chambers : 20 • The heart muscle. • Myocardium

  5. Coverings, Layers & Chambers : 30 • Serous layer covering the heart muscle. • Epicardium • 10 pt. BONUS: Another name for this layer. • Visceral layer

  6. Coverings, Layers & Chambers : 40 • The outermost layer of the serous pericardium. • Parietal Layer

  7. Coverings, Layers & Chambers : 50 • Which layer of the heart actually contracts? • Myocardium

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

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

  11. Pathway of Blood: 40 • Vessels that return blood to the heart. • Pulmonary veins

  12. Pathway of Blood : 50 • Cardiac veins return blood to this location before the blood enters the right atrium. • Coronary Sinus

  13. Heart Valves: 10 • Prevents backflow into the left ventricle • Aortic valve

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

  15. 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. Heart Valves: 40 • 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

  19. Properties of Cardiac Muscle: 10 • Compare Skeletal & Heart Muscle: • Answer: Skeletal Muscle only, Cardiac Muscle only, or Both • Has Striations • Both

  20. Properties of Cardiac Muscle: 20 • Compare Skeletal & Heart Muscle: • Answer: Skeletal Muscle only, Cardiac Muscle only, or Both • Contains self-excitable cells • Cardiac Muscle only

  21. Properties of Cardiac Muscle: 30 • Why is the heart a functional syncytium? • The heart contracts as a unit (all or none) or it doesn’t contract at all.

  22. Properties of Cardiac Muscle : 40 • What cell membrane junction allows the myocardium to function as a functional syncytium? • Gap junctions

  23. Properties of Cardiac Muscle: 50 • TRUE or FALSE: • Cardiac muscle has more mitochondria and depends less on a continual supply of oxygen than does skeletal muscle. • FALSE – O2 is essential

  24. RANDOM! : 10 • Where does the myocardium receive its blood supply from? • Coronary arteries

  25. RANDOM! : 20 • What structure is labeled with the star? • Right Atrium

  26. RANDOM! : 30 • What valve is between the left atrium and the left ventricle? • Mitral (bicuspid) valve

  27. RANDOM! : 40 • What is the chamber that receives blood from the superior and inferior vena cava? • Right atrium

  28. RANDOM! : 50 • What structures are labeled in the picture? • Chordae tendinae

  29. Final Jeopardy • Name the laeled structure. • Papillary muscle
