1 Circulatory System

2 How does the Heart work?

3 4 Chambers Atrium Atrium Right Side Left Side Ventricle Ventricle

4 4 Valves Mitral Tricuspid Aortic Pulmonary

5 Just 13 Steps for the Pathway Of Circulation

6 1. Superior & Inferior Vena Cava (largest veins)

7 2. Right Atrium

8 3. Tricuspid Valve

9 4. Right Ventricle

10 5. Pulmonary Valve

11 6. Pulmonary Artery

12 7. LUNGS

13 8. Pulmonary Veins

14 9. Left Atrium

15 10. Mitral Valve

16 11. Left Ventricle

17 12. Aortic Valve

18 13. Aorta (largest artery)

19 Thick muscle that divides
the right & left side of the heart = Septum

20 Common Heart Problems Heart Valve Problems
Stenotic Valve- hardened valve restricting blood flow Regurgitation- “leaky valve” valve does not close tightly Heart Chamber Problems Systolic Heart Failure- weak or enlarged heart causing left ventricle to lose its ability to contract. Diastolic Failure- the chamber becomes stiff and loses its ability to relax and fill with blood Artery Problems Coronary Artery Disease- arteries supplying blood to heart become hardened and narrowed. Rhythm Problems Arrhythmias- irregular heartbeat due to disruption of normal electrical rhythm of the heart. Circulatory Problems Heart Attack- reduced blood flow to the heart causing damaged heart muscle. Stroke- reduced blood flow to the brain causing damaged brain cells.
