5 Matching questions

  1. Hypertension
  2. factors that aid in venous return
  3. Elastic (Conducting) Arteries
  4. What is Systolic Pressure?
  5. Antidiuretic Hormone
  1. a Respiratory pump, muscular pump and vasconstriction of veins under sympathetic control.
  2. b Pressure exerted on arterial walls during ventricular contraction.
  3. c High blood pressure, sustained elevated arterial pressure of 140/90 or higher. May be transient adaptations during fever, physical exertion, and emotional upset. Often persistent in obese people.
  4. d Thick walled arteries near the heart. Act as pressure reservoirs - expand and recoil as blood is ejected from the heart.
    Conduct blood from the heart into Muscular Arteries.
  5. e (ADH)-(Vasopressin) - Causes intense vasoconstriction in cases of extremely low BP. Increases BP.

5 Multiple choice questions

  1. Distal to elastic arteries, deliver blood to body organs, have thick tunica media with more smooth muscle, active in vasoconstruction to adjust the rate of blood flow; Distribute blood to Arterioles.
  2. (MAP), average pressure in the arteries.
  3. Causes BP to drop by inhibiting ADH.
  4. The friction between blood and blood vessel walls.
  5. Small-diameter arterioles.

5 True/False questions

  1. the three important sources of vascular resistanceThe friction between blood and blood vessel walls.

          

  2. funciton of Capillarieslack pores and have a intercelluar clefts that allow only diffusion of water and small solutes.

          

  3. Nitric OxideSmall arteries that lead into capillary beds; controls blood flow into capillary beds by vasodilation and vasoconstriction; Deliver blood to capillaries.

          

  4. Tunica Media's functionSmooth muscle and elastic fiber layer, regulated by sympathetic nervous system.

          

  5. What does Atherosclerosis effect?Pressure exerted on arterial walls during ventricular contraction.
