  1. Which of the following are places where nutrients and wastes are exchanged between the blood and the interstitial fluid of the tissues?
    Capillaries
  2. Auricles are part of the:
    Atria
  3. The function of the chordae tendineae is to
    keep the valves between the atria and ventricles closed at the right time
  4. Which of the chambers of the heart has the thickest wall?
    Left Ventricle
  5. Which of the following has the structures listed in the order that blood could pass through them on a trip from the fight atrium back to the right atrium?
    Right Ventricle, pulmonary vein, bicuspid valve, aorta
  6. How many flaps does each semilunar valve have?
    3
  7. In the fetus, the ductus arteriosus provides a passageway between the
    aorta and pulmonary artery
  8. What vein is formed by the union of the superior mesenteric vein and the splenic vein?
    Hepatic portal vein
  9. Capillaries have a diameter that lets how many red blood cells through at a time?
    1
  10. Chordae tendineae are attached to
    atrioventricular valves and papillary muscles
  11. The coronary arteries are branches of the
    ascending aorta
  12. In Vasodilation, _____________ of smooth muscle __________________ the size of the lumen.
    relaxation, increases

    In Vasodilation, __relaxation___________ of smooth muscle ____increases______________ the size of the lumen.
  13. A feature of arteries that helps maintain continuous flow is
    elastic fibers in the walls
  14. The components of the ______ are the heart, blood vessels, and blood.
    circulatory system
  15. In the adult, the pulmonary arteries carry
    deoxygenated blood
  16. The scientific name for a blood pressure cuff is a
    sphygmomanometer

    sph-yg-mom-ano-meter
  17. If someone has a blood pressure of 120/80, then 80 is the _________ blood pressure and indicates the pressure when the ventricle ________
    • If someone has a blood pressure of 120/80, then 80 is the __diastolic_______
    • blood pressure and indicates the pressure when the ventricle _relaxes_______
  18. Resistance in the circulatory system is primarily the result of friction between
    The blood and the blood vessel walls
  19. The hepatic portal vein is a portal vein because it carries blood between
    two capillary networks
  20. In people, the left brachiocephalic vein is formed by the junction of the left subclavian vein and the
    left internal jugular vein
  21. The branch of the aorta that carries blood to the stomach, liver, and spleen is the
    Celiac artery
  22. If someone has a blood pressure reading of 145/79, what would his/her mean blood pressure be?
    • 145-79=66
    • 66/3=22

    Thus 79+22=101
  23. A vascular or venous sinus differes from a regular vein because it has no
    muscle layer
  24. The volume of blood in an adult is approimately
    5 liters
  25. What makes the semilunar valves close?
    pressure of blood returning to the heart as it relaxes
  26. Smooth muscles in the metarterioles help control blood flow through the
    capillaries
  27. Which of the following describes the velocity of the blood as it goes form the aorta through the capillaries and back to the heart?
    Decreases and then increases
  28. When a blood vessel branches, the branches together have _____ the original vessel.
    More cross-sectional area than

    When a blood vessel branches, the branches together have _More cross-sectional area than____ the original vessel.
  29. Connetions between blood vessels that provide alternate routes are called
    anastomoses

    an-ast-omo-ses
  30. List one factor discussed in class that will increase the resistance in the circulatory system.
    • Longer vessel length
    • Smaller vessel radius
    • Higher blood viscosity
  31. Capillaries are composed of endothermic and what other layer.
    basement membrane
  32. The muscle layer of the heart wall is called the
    myocardium

    my-o-card-ium
  33. State Henry's Law.
    The quantity of a gas that will dissolve in a liquid is proportional to the partial pressure of the gas and the solubility coefficient of the gas.
  34. State Boyle's Law
    The volume of a gas varies inversely with its pressure.
  35. The pressure of air between the lining of the chest wall, the parietal pleura and the lining that covers the lungs, visceral pleura
    Intrapleural pressure
  36. When does Inspiration occur?
    Inspiration occurs when alveolar pressure is below atmospheric pressure, aka an inhalation
  37. What occurs when alveolar pressure is above atmospheric pressure
    Expiration occurs when alveolar pressure is above atmospheric pressure
  38. The amount of air moved in and out with normal breathing.
    Tidal Volume
  39. Tidal Volume is usually about __ mL in adults
    500 mL
