  1. T/F
    arteries and corresponding veins don't usually travel together so they have different names
    FALSE. usually travel together so get similar names!
  2. T/F
    the blood in veins are fully deoxygenated
    FALSE. the blood in veins are "partially" deoxygenated = doesn't mean no oxygen, there is still some
  3. 2 circulations of the cardiovascular system
    • because of 2 pumps
    • 1. pulmonary
    • 2. systemic
  4. 3 clog routes
    • 1. lungs
    • 2. heart
    • 3. brain
    • *start: veins are where clots tend to form
  5. 4 types of drug routes
    • 1. ingested
    • 2. injected
    • 3. inhaled
    • 4. absorbed
  6. the route of absorption
    • (1) digestive organs --> (2) Hepatic portal vein --> (3) liver = first pass effect (metabolize to activate/inactivate/changes the delivered drugs) --> (4) hepatic veins --> (5) inferior vena cava --> (6) heart
    • *if skips liver = less of drug
  7. Heart inputs/outputs from Upper torso/body veins
    (1) upper torso/body veins --> (2) Superior vena cava --> (3) right atrium --> (4) right ventricle --> (5) pulmonary arteries --> (6) lungs --> (7) pulmonary veins --> (8) left atrium --> (9) left ventricle --> (10) ascending aorta
  8. Heart inputs/outputs from Lower torso/body veins
    (1) lower torso/body veins --> (2) Inferior vena cava --> (3) right atrium --> (4) right ventricle --> (5) pulmonary arteries --> (6) lungs --> (7) pulmonary veins --> (8) left atrium --> (9) left ventricle --> (10) ascending aorta
  9. location of the carotids (arteries)
    • on the sides of the trachea (neck area)
    • *can feel pulse here
  10. path of aorta to brain (arteries)
    (1) ascending aorta --> (2) aortic arch --> (3) branches to a) brachiocephalic trunk and b) left carotid --> (4) a) goes to right carotid --> (5) both goes to the brain --> (6) reaches the right and left middle cerebral arteries --> (7) both reaches the anterior and posterior communicating arteries
  11. cause of stroke/CerebroVascular Accident (CVA) in middle cerebral arteries
    blockage (clots)
  12. cause of stroke/CerebroVascular Accident (CVA) in communicating arteries
    aneurysm (hemorrhage)
  13. path of brain to heart (veins)
    (1) brain --> (2) right and left jugular --> (3) right and left brachiocephalic trunk --> (4) superior vena cava --> (5) heart
  14. heart to arms (arteries)
    (1) ascending aorta --> (2) aortic arch --> (3) branches to a) brachiocephalic trunk, b) left carotid, c) left subclavian --> (4) brachiocephalic trunk branches to right carotid and right subclavian --> (5) subclavian arteries go to arms
  15. heart to hand (arteries)
    • right side: (1) heart --> (2) ascending aorta --> (3) aortic arch --> (3) brachiocephalic trunk --> (4) a) right carotid, b) right subclavian --> (5) right subclavian to axillary --> (6) brachial --> (7) ulnar and radial --> (8) hand
    • left side: (1) heart --> (2) ascending aorta --> (3) aortic arch --> (4) branch to a) left carotid, b) left subclavian --> (5) left subclavian to axillary --> (6) brachial --> (7) ulnar and radial --> (8) hand
  16. hand to heart (veins)
    • inner path: (1) hand --> (2) ulnar and radial --> (3) brachial --> (4) axillary --> (5) subclavian veins --> (6) brachiocephalic --> (6) superior vena cava --> (7) heart
    • outer path: (1) hand --> (2) a) cephalic, b) basilic --> (3) cephalic to a) right subclavian, b) median cubital and basilic to axillary --> (4) median cubital to basilic --> (5) axillary to right subclavian --> (6) brachiocephalic trunk --> (7) superior vena cava --> (8) heart
  17. T/F
    veins and arteries are 100% symmetrical
    • FALSE. veins have surface veins
    • arms: cephalic, median cubital, basilic
    • legs: great and small saphenous
  18. 4 benefits for surface veins
    • 1. thermoregulation
    • 2. transfusions
    • 3. phlebotomy
    • 4. intravenous therapy
  19. 4 purposes of Central Line
    • aka Central Venous Catheter (vein --> vena cave/right atrium)
    • 1. allow for more concentrated medications
    • - some meds bad for tissues around small veins
    • 2. rapid administration of high volume fluid
    • - IV fluid, blood, plasma
    • 3. Total Parenteral Nutrition
    • - stay in vein longer
    • 4. test for oxygen saturation or venous pressure
    • *use PICC line: peripherally inserted central catheter
    • -cephalic, basilic, brachial
  20. heart to trunk (arteries)
    (1) heart --> (2) ascending aorta --> (3) descending aorta --> (4) thoracic aorta --> (5) abdominopelvic aorta --> (6) iliacs
  21. heart to leg (arteries)
    (1) heart --> (2) ascending aorta --> (3) descending aorta --> (4) thoracic aorta --> (5) abdominopelvic aorta --> (6) iliacs --> (7) femoral --> (8) popliteal --> (9) tibial and fibular --> (10) feet
  22. leg to heart (veins)
    • inner path: (1) leg --> (2) tibial and fibular --> (3) popliteal --> (4) femoral --> (5) iliacs --> (6) inferior vena cava --> (7) heart
    • outer path: (1) leg --> (2) a) great saphenous, b) small saphenous --> (3) great saphenous to iliacs --> (4) small saphenous to popliteal --> (5) popliteal to femoral to iliacs --> (6) inferior vena cave --> (7) heart
