Show Answers:

  1. Cardiovascular system derives from _
  2. Formation of the heart starts with formation of paired _ in cephalic region of embryo
    Endocardial tubes
  3. Truncus arteriosus forms _
    Proximal aorta and proximal pulmonary artery
  4. Bulbus cordis forms _
    Smooth parts of right ventricle (conus arteriosus) and left ventricles
  5. Primitive ventricle forms_
    Right and left ventricles
  6. Prmitive atrium forms _
    Right and left atria
  7. Sinus venosus forms _
    Smooth part of right atrium, coronary sinus and oblique vein
  8. Aberrant development of aorticopulmonary septum is responsible for _
    Tetralogy of Fallot
  9. Most common type of atrial septal defect
    Patent foramen ovale
  10. The lumen of truncus arteriosus and bulbus cordis is divided into aorta and pulmonary trunk by _
    Aorticopulmonary septum
  11. Septum primum, septum secundum and AV cushion form _
    Atrial septum
  12. Communication between right and left atria that is formed by the walls of septum primum and septum secundum
    Foramen ovale
  13. Allows blood to flow from venous side of circulation to arterial without
    passing through the lungs as result of higher pressure on venous side
    during gestation
    Foramen ovale
  14. Why does foramen ovale close after birth
    Because of increased arterial pressure which pushes spetum primum against atrial septum
  15. Aorticopulmonary septum, right and left bulbar ridges and AV cushion form _
    Interventricular septum
  16. This arch helps forming adult common carotid arteries bilaterally
    Arch 3
  17. This arch helps forming AORTA on the left and proximal subclavian artery on the right
    Arch 4
  18. This arch helps to form DUCTUS ARTERIOSUS and part of PULMONARY TRUNK
    Arch 6
  19. One of the only places in the body (along with pulmonary circulation) where an ARTERY DOES NOT CARRY OXYGENATED BLOOD
    • UMBILICAL CIRCULATION - paired umbilical arteries carry deoxygenated
    • blood to the placenta while UMBILICAL VEIN brings oxygenated blood back
    • to the fetus
  20. _ vein gives rise to ligamentum teres hepatis
    Left umbilical vein
  21. _ veins help form internal jugular vein and superior vena cava
    Anterior cardinal veins
  22. _ veins help form inferior vena cava, common iliac veins, azygos vein, and renal veins
    Posterior cardinal veins
  23. _ veins help form ductus venosus and hepatic sinusoids, inferior vena cava, portal vein, superior and inferior mesenteric veins
    Vitelline veins
