Study Notes

Blood Vessel Quiz Notes

  • Question 1: The Celiac trunk is the vessel that blood does not flow through on its way from the ascending aorta to the dorsalis pedis.
  • Question 2: The descending aorta is the vessel that blood does not flow to on its path from the hepatic vein to the brachial artery
  • Question 3: The aorta is the largest artery, and is the originator of most other arteries.
  • Question 4: Both vertebral and common carotid arteries supply oxygenated blood to the circle of Willis. These arteries drain into the jugulars.
  • Question 5: The carotid artery supplies the head and neck region.
  • Question 6: Both the aortic arch and the right brachiocephalic arteries give rise to the left and right common carotid arteries.
    • The aortic arch and right brachiocephalic arteries do not arise from coronary arteries.
    • These arteries do not deliver contents to the jugulars.
    • The arteries do not receive oxygenated blood from the circle of Willis.
  • Question 7: The umbilical vein has the highest oxygen concentration in fetal blood vessels.
  • Question 8: Blood flow from the placenta to the inferior vena cava is via the umbilical vein, and then the ductus venous.
  • Question 9: Both vertebral and internal carotid arteries deliver oxygenated blood to the brain.
  • Question 10: Arteries carry blood away from the heart. They contain no valves. Arteries are usually color-coded red.
  • Question 11: The subclavian vein carries blood from the axillary vein to the right atrium.
  • Question 12: The circle of Willis is the arterial blood supply to the brain. It is supplied by the internal carotid and vertebral arteries. Oxygenated blood is not delivered to the circle of Willis by the jugulars.
  • Question 13: Blood pressure is lowest in the inferior vena cava.
  • Question 14: The subclavian artery is a branch of the aorta that supplies the upper extremity.
  • Question 15: The saphenous vein extends from the foot to the thigh.
  • Question 16: Common iliac veins drain blood into the inferior vena cava.
  • Question 17: The foramen ovale allows blood to shunt from the left atrium to the right atrium during fetal development
  • Question 18: The placenta is the fetal "lungs".
  • Question 19: Hepatic veins carry unoxygenated blood from the liver to the inferior vena cava.
  • Question 20: The right common carotid artery is not a vessel supplying blood from right axillary vein to the right atrium.
  • Question 21: The hepatic portal system, along with the hepatic artery and hepatic veins are associated with hepatic circulation.
  • Question 22: Vertebral arteries merge to form the basilar artery.
  • Question 23: Capillaries have a single layer of epithelium allowing for fluid transport between blood and tissues.
  • Question 24: The diffusion of oxygen from the blood into the tissues is the function reflected by capillary color changes.
  • Question 25: The ductus venosus connects the umbilical vein with the inferior vena cava.
