2. Pre-Dissection Drawing Activity Pathway of Blood Through Heart

3. Supplies: large sheet of paper pencil 3 fine tip colored markers (blue, red, green) Optional: highlighter (pink or orange)

4. The heart is a double pump. Right Heart Pump Left Heart Pump

5. The heart is a double pump. Right Heart Pump Left Heart Pump

6. The right heart pumps venous (deoxygenated) blood. Right Heart Pump

7. The left heart pumps arterial (oxygenated) blood. Left Heart Pump

8. Drawing the right heart. Right heart

9. Turn your paper to landscape Fold your paper so that the outside edges meet in the middle

10. Step 1: Draw outline of heart. Middle of heart should be next to the opening Right sideLeft side apex

11. Step 2: Draw myocardium & septum. Identify chambers. Rt. sideLf. side apex septum myocardium RA RV LA LV

12. Step 3: Draw both superior & inferior vena cavae apex Rt. sideLf. side superior vena cava inferior vena cava septum LA RA RV LV

13. Step 4: Draw tricuspid valve. superior vena cava Rt. sideLf. side inferior vena cava apex septum tricuspid valve LV RV RA LA

14. Step 5: Draw pulmonary artery. Rt. sideLf. side superior vena cava tricuspid valve inferior vena cava septum apex LV RV RA LA pulmonary artery

15. Step 6: Draw pulmonary valve. LV RV RA LA superior vena cava Rt. side Lf. side pulmonary artery tricuspid valve inferior vena cava septum apex pulmonary valve

16. Step 7: Outline great vessels & chambers with blue marker. LV RV RA LA superior vena cava Rt. sideLf. side pulmonary artery tricuspid valve inferior vena cava septum apex pulmonary valve

17. Step 8: Outline valves in green. Color septum & myocardium in pink. RV RA LA LV superior vena cava Rt. sideLf. side pulmonary artery tricuspid valve inferior vena cava septum apex pulmonary valve

18. Step 9: Indicate pathway of blood through right heart with arrows. RV RA LA LV superior vena cava Rt. sideLf. side pulmonary artery tricuspid valve inferior vena cava septum apex pulmonary valve

19. Drawing the left heart. Left heart

20. Step 1: Draw outline of heart. Rt. sideLf. side apex

21. Step 2: Draw the myocardium and septum Rt. sideLf. side apex septum myocardium RA RV LA LV

22. Step 3: Draw mitral valve. Rt. sideLf. side myocardium septum apex RA LA RV LV mitral valve

23. Step 4: Draw aorta. RA LA LV RV Rt. sideLf. side myocardium septumapex mitral valve aorta

24. Step 5: Draw aortic valve. RA LA LV RV Rt. sideLf. side myocardium septumapex mitral valve aorta aortic valve

25. Step 6: Draw pulmonary veins. Rt. sideLf. side aorta LA RA RV LV myocardium septum aortic valve mitral valve apex pulmonary veins

26. Step 7: Outline great vessels & chambers with red marker. Rt. sideLf. side aorta pulmonary veins aortic valve myocardium septumapex mitral valve LA LV RA RV

27. Step 7: Outline valves in green. Color septum & myocardium in pink. aorta Rt. side Lf. side pulmonary veins aortic valve myocardium septumapex mitral valve LA RA RV LV

28. Step 7: Indicate pathway of blood through left heart with arrows. aorta Rt. side Lf. side pulmonary veins aortic valve myocardium septumapex mitral valve LA RA RV LV

29. Final Step: Draw entire heart.
