Heart of My Heart (Solution)

ACROSS
1. backward blood flow: regurgitation

3. myocyte pumping action: contractility

5. semilunar valve, not aortic: pulmonary

8. obstruction of forward blood flow: stenosis

10. dense connective tissue layer in normal valve leaflet: fibrosa

12. increase in cell number in response to injury: hyperplasia

15. myocyte relaxation: compliance

16. fibrous and parietal: pericardium

17. atrioventricular valve, not mitral: tricuspid

18. terminal conduction fibers: Purkinje

19. tissue response to disuse: atrophy

DOWN
2. conduction junction (2 words): intercalated disc

4. cardiac mesothelium: epicardium

6. replacement of one cell type by another in response to injury: metaplasia

7. retrograde movement of valve leaflet: prolapse

9. flexible loose connective tissue layer in normal valve: spongiosa
