  6. Blood within the pulmonary veins returns to the?
    left atrium
  7. Blood is carried to capillaries in the myocardium by way of the
    coronary arteries

    Tunica Intimae
  9. Choose the blood vessel responsible for draining the majority of blood from the brain?
    internal jugular veins
  10. Functionally there are no valves in arteries because:
    The blood pressure in arteries is high enough that there is no risk of backflow of blood
  11. What vessel in the fetus connects the pulmonary trunk to the aortic arch so that much of the blood bypasses the immature lungs
    ductus venosus

    Aortic arch
    subclavian artery
    axilary artery
    brachial artery
    Brachiocephalic artery
  14. Most systemic venous blood is both oxygen poor and nutrient poor. However systemic venous blood that is oxygen poor and nutrient rich occurs in
    the hepatic portal vein
  15. The three arteries that branch from the aortic arch are in order the
    brachiocephalic, left subclavian, and left common carotid arteries.
  16. Which artery arises from the inferior part of the abdominal aorta and supplies the distal end of the large intestines?
    inferior mesenteric artery
  17. Which vessel is missing from the following statement: “Tracing blood that drains from the large intestine, we find that blood leaves the intestinal capillaries and passes through the superior mesenteric vein, the hepatic vein, the liver sinusoid capillaries and the inferior vena cava”
    celiac vein

    AV valve
    SA node
    AV mode
    AC bundle
    AV valve
  28. Which branch of the abdominal aorta supplies the stomach
    gastroduodenal &celiac trunk
  29. Which of the following are involved in the pulmonary circulation?
    right ventricle, pulmonary artery, left atrium
