3. Overview The right side receives oxygen-poor blood
The heart=a muscular double pump with 2 functions
Overview
The right side receives oxygen-poor blood
Its left side receives oxygenated blood from lung, sends to rest of body

4. Heart’s position in thorax

6. CXR (chest x ray)
Normal male

7. Chest x rays
Normal female
Lateral (male)

8. Pericardium -outer membrane enclosing the heart
Starting from the outside…
Pericardium -outer membrane enclosing the heart
Without most of pericardial layers

9. Layers of the heart wall
Epicardium- outer layer, protects the heart by reducing friction

10. Layers of the heart wall
Epicardium- outer layer, protects the heart by reducing friction
Myocardium- consists of cardiac muscle tissue, pumps heart

11. Layers of the heart wall
Epicardium- outer layer, protects the heart by reducing friction
Myocardium- consists of cardiac muscle tissue, pumps heart
Endocardium- inner lining of the heart, contains blood vessels and elastic fibers

13. Layers of pericardium and heart wall

14. Chambers of the heart sides are labeled in reference to the patient facing you
Two atria
Right atrium
Left atrium
Two ventricles
Right ventricle
Left ventricle

15. Septum Interatrial Septum- Wall separating right and left Atria
Interventricular Septum- Wall separating right left ventricle

17. Function of AV valves

19. Superior Vena Cava
Vein that carries deoxygenated blood from upper body to the Right Atrium.
Such as arms, neck, and head.

20. Inferior Vena Cava
Vein that carries deoxygenated blood from lower body to the Right Atrium.
Such as legs and lower torso

21. Pulmonary Artery
Carries blood from Right Ventricle to the lungs to be oxygenated
Splits into Right and Left for each lung.

22. Pulmonary Veins
Carries oxygenated blood from lungs back into the heart’s Left Atrium

23. Aorta
Arched artery from Left Ventricle that supplies body with oxygenated blood
Ascending arteries supply upper body
Descending supplies lower body

24. Valves
Pulmonary Valve
Connects Right Ventricle to Pulmonary artery

25. Valves
Aortic Valve
Connects Left Ventricle to Aorta

26. Valves
Tricuspid Valve
Boundary between right Ventricle and atrium

27. Valves
Mitral Valve
Connects Left Ventricle and Atrium

33. Embryological development during week 4 (helps to understand heart defects)
(day 23)
(day 28)
(day 24)
Day 22, (b) in diagram, heart starts pumping

34. Simplified flow: print and fill in details

35. Flow chart

37. LEFT SIDE ACTIVITY
Draw the heart with all the valves and arteries. Label them all and trace the flow of blood through the heart. Use red arrows to indicate deoxygenated blood and blue arrows to indicate oxygenated blood.
