Cardiovascular System

  1. Arteries:
    Carotid Subclavian, Aorta, Brachial, Radial, Iliac, Femoral,
  2. Veins:
    Jugular, Subclavian, Superior Vena Cava, Cephalic, Inferior Vena Cava, Femoral
  3. HEART:
    Superior Vena cava, Pulmenary Artery, Pulmenary Vein, Right Atrium, Right Ventrical, Inferior Vena Cava Aorta, Left Ventricle, Left Atrium, Aorta
  4. Blood Plasma 55%:
    • Water 90%
    • Proteins 8%
    • Organic Acids 1%
    • Salts 1%
  5. Blood Cells 45%:
    • Leucocytes & Platelets 2.3%
    • Erythrocytes 97.7%
  6. Blood Before Birth:
    Spleen, Liver, Red Bone Marrow
  7. Blood After Birth:
    Red Bone Marrow
  8. Erythrocytes last 90-120 days
  9. More Erythrocytes then Leucocytes?
    We need more oxygen in our bodies then defenses against harmful things
  10. Blood Typing:
    Few drops of blood dropped on slide, antigen A is placed to see if agglutination takes place. If it doesnt, then antigen B is placed on other drop of blood. If there is no agglutination then it is blood type O. If little agglutination then its AB.
  11. Flow of Blood through the Heart and Lungs and Body:
    Blood goes through the right atrium from the vena cava. Then to right ventricle then through pulminary artery to the lungs where it is oxygenated, and then back to heart through pulmonary vein. Then received into the left atrium and then goes to the left ventricle. Then pumped through the aorta and body.
  12. Heart Beat?:
    Electrical impulses causes the atria to contract, the another nerve impulse causes the ventricles to contract as the atria relaxes and fills with blood.
  13. Two numbers given in Blood Pressure reading?:
    • 120/180
    • Systolic Pressure-pressure of blood during heart contraction
    • Dinstolic Pressure-pressure of blood during heart relaxation
  14. Blood Clotting:
    Plates secrete thrimbosplastin on rough edges of damaged part. When calcium and protein from blood plasma come in contact with the throthrombin it becomes thrombin. When when the thrombin comes in contact with another plasma substance called fibrinogen it becomes fibrin.The fibrin binds itself wtih he blood cells and platelets in that region to become the blood clot.
