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

4. Two circulations
Systemic circuit: blood vessels that transport blood to and from all the body tissues
Pulmonary circuit: blood vessels that carry blood to and from the lungs

5. Heart’s position in thorax

7. CXR (chest x ray)
Normal male

8. Chest x rays
Normal female
Lateral (male)

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

10. 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

12. Layers of pericardium and heart wall

13. 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

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

16. Function of AV valves

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

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

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

21. Pulmonary Veins Total of 4 Pulmonary Veins (2 from each lung)
Carries oxygenated blood from lungs back into the heart’s Left Atrium

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

23. Valves
Pulmonary Valve
Connects Right Ventricle to Pulmonary artery

24. Valves
Aortic Valve
Connects Left Ventricle to Aorta

25. Valves
Tricuspid Valve
Boundary between right Ventricle and atrium

26. Valves
Mitral Valve
Connects Left Ventricle and Atrium
