  1. Cardiovascular System Gretchen Sharpe-Swart Coulson Jensen Haley Wangberg

  2. Composition: • Heart: The organ that pumps the blood throughout the body • Veins: Transports oxygen deficient blood to heart and lungs • Arteries: Transports oxygen rich blood throughout the body • Blood: The fluid consisting of plasma, blood cells, and platelets that is circulated by the heart carrying oxygen and nutrients to and waste materials away from all body tissues.

  3. Heart: Anatomy • 1. Right Coronary • 2. Left Anterior Descending • 3. Left Circumflex • 4. Superior Vena Cava • 5. Inferior Vena Cava • 6. Aorta • 7. Pulmonary Artery • 8. Pulmonary Vein • 9. Right Atrium • 10. Right Ventricle • 11. Left Atrium • 12. Left Ventricle • 13. Papillary Muscles • 14. ChordaeTendineae • 15. Tricuspid Valve • 16. Mitral Valve • 17. Pulmonary Valve • Aortic Valve (Not pictured)

  4. Heart: Anatomy Info • Right Coronary and Left Coronary: The coronary arteries are the network of blood vessels that carry oxygen- and nutrient-rich blood to the cardiac muscle tissue. • Superior Vena Cava: Veins from the head and upper body feed into the superior vena cava, which empties into the right atrium of the heart • Inferior Vena Cava: Veins from the legs and lower torso feed into the inferior vena cava, which empties into the right atrium of the heart • Aorta: The largest single blood vessel in the body. It is approximately the diameter of your thumb. This vessel carries oxygen-rich blood from the left ventricle to the various parts of the body • Pulmonary Artery: The vessel transporting de-oxygenated blood from the right ventricle to the lungs • Pulmonary Vein: The vessel transporting oxygen-rich blood from the lungs to the left atrium

  5. Heart Anatomy Cont. • Atrium: The right atrium receives de-oxygenated blood from the body through the superior vena cava (head and upper body) and inferior vena cava (legs and lower torso) and pumps to the ventricle • Ventricle: The right ventricle receives de-oxygenated blood as the right atrium contracts. Pumps to the pulmonary valve which allows the blood to flow into the pulmonary artery toward the lungs • Papillary Muscles: The papillary muscles attach to the lower portion of the interior wall of the ventricles • ChordaeTendineae: The chordaetendineae are tendons linking the papillary muscles to the tricuspid valve in the right ventricle and the mitral valve in the left ventricle

  6. Heart Anatomy Cont. • Tricuspid Valve: The tricuspid valve separates the right atrium from the right ventricle. It opens to allow the de-oxygenated blood collected in the right atrium to flow into the right ventricle • Mitral Valve: The mitral valve separates the left atrium from the left ventricle. It opens to allow the oxygenated blood collected in the left atrium to flow into the left ventricle • Pulmonary Valve: The pulmonary valve separates the right ventricle from the pulmonary artery. As the ventricles contract, it opens to allow the de-oxygenated blood collected in the right ventricle to flow to the lungs • Aortic Valve: The aortic valve separates the left ventricle from the aorta. As the ventricles contract, it opens to allow the oxygenated blood collected in the left ventricle to flow throughout the body

  7. Blood Flow

  8. Blood composition: • The blood carries oxygen and essential nutrients to all of the living cells in the body, and also carries waste products to systems that eliminate them. Most of the blood is made up of a watery, protein-laden fluid called plasma. A little less than half of this blood volume is composed of red and white blood cells, and other solid elements called platelets. • Platelets are responsible for coagulation of blood at the point of an injury to a blood vessel. Without platelets, our blood would not be able to clot and hemorrhaging or uncontrolled bleeding would result.

  9. Lab • With a partner, measure your pulse and heart rate. • Find your pulse either in your neck or your wrist. • For 15 seconds, count your heartbeats and multiply that number by four

  10. Random Facts • The average adult has between 5 to 6 liters of blood or blood volume. • Hemophilia is a genetic condition, which results in individuals with no ability to clot. Also called bleeders, these individuals must periodically administer a clotting factor to their blood to prevent the constant bleeding, which occurs. • A systolic blood pressure of 120 millimeters of mercury is considered right in the middle of the range of normal blood pressures, as is a diastolic pressure of eighty. In common terms, this normal measurement would be stated as "120 over 80".
