“Heart Smarts” Anatomy of the Heart

1. “Heart Smarts” Anatomy of the Heart Pumps your Blood John Peters, EMT-LP Hereford High School

2. Identify the 4 chambers, the 2 sides and 4 valves of the heart Define the medical terms associated with the heart Discuss how the blood flows through the heart Distinguish between the Right and Left side of the heart Understand where the blood flows after it leaves the heart (Lungs and Body) Compare and contrast Oxygenated and Deoxygenatedblood Do you know these already? You will by the end of this class!

3. The Heart is an Organ • The heart has two sides, the Right and Left separated by the Septum • The heart has upper and lower chambers, the Atria and the Ventricles

4. The 2 Sides of the Heart • The right side of the heart – to the lungs • The left side of the heart – to the body • The upper and lower chambers of the heart • The Atria • The Right AtriumandtheLeft Atrium • The Ventricles • The Right Ventricleand theLeft Ventricle

5. Distinguish between the Right and Left side of the heart The Right side of the heart pumps Deoxygenated bloodto the lungs A Low Pressure Pump Separated by the Septum The Left side of the heart pumps Oxygenated bloodto the body A High Pressure Pump The Left side of the heart is larger and thicker than the right side of the heart (3 times as thick)

6. The 4 Valves of the Heart Tricuspid Pulmonary Mitral (Bicuspid); and Aortic Mnemonic - T P M A

7. Right Side Verse #1 Superior and Inferior Vena Cava Right Atrium Tricuspid Valve Right Ventricle Pulmonary Valve Pulmonary Arteries Lungs Left Side Verse #2 Pulmonary Veins Left Atrium Bicuspid/Mitral Valve Left Ventricle Aortic Valve Aorta - Arteries The Body Cardiac Terminology(Medical Terminology)

8. Cardiac Terminology(Medical Terminology) Continued • Arterioles • Capillaries where the O2 and CO2exchange – a process known as“internal respiration” as opposed to“external respiration” when we breathe • Venules • Veins • Superior and Inferior vena cava

9. After the Oxygenated blood leaves the heart where does it go? • Aorta • Arteries • Arterioles • Capillaries • Cells Internal Respiration

10. "PUMP YOUR BLOOD" SONG VERSE ONE Pump, pump, pumps your Blood. The Right atrium’s where the process begins, where the CO2 Blood enters the heart. Through the tricuspid valve, to the Right ventricle, the pulmonary artery, and lungs. Once inside the lungs, it dumps its carbon dioxide and picks up its oxygen supply. Then it’s back to the heart through the pulmonary vein, through the atrium and Left ventricle. Pump, pump, pumps your Blood.

11. After the body uses the oxygen and nutrients where does the deoxygenated blood go? • Cells • Venules • Veins • Pulmonary Vein

12. "PUMP YOUR BLOOD" SONG - VERSE TWO Pump, pump, pumps your Blood. The aortic valve’s, where the Blood leaves the heart, then channeled to the rest of the bod. The arteries, arterioles, and capillaries too bring the oxygenated Blood to the cells. The tissues and the cells trade off waste and CO2, which is carried through the venules and the veins, through the larger vena cava to the atrium and lungs, and we're back to where we started in the heart. Pump, pump, pumps your Blood.

13. Blood Discuss the difference between: • Deoxygenated • Oxygenated

14. Do you know the two sides of the heart? Do you know the names of the upper and lower chambers of the heart? Do you know the 4 valves of the heart? Do you know what is deoxygenated blood? Do you know what is oxygenated blood? Do you know how the blood flows through the heart? Do you know how the blood flows through the circulatory system? Do you know?Summary

15. Practice • Worksheet • Label the diagram, use the words from the song and the Heart Anatomy Glossary to track the flow of blood through the heart. • Music Contest • Develop a new version of the “Pumps Your Blood” song. The winner will get to make a music video and have it posted as a Podcast on the school website.

16. Have a Great Day!
