5 Matching questions

  1. What is Diastolic Pressure?
  2. Arterioles
  3. What is Systolic Pressure?
  4. Inflammatory Chemical
  5. Angiotensin II
  1. a Small arteries that lead into capillary beds; controls blood flow into capillary beds by vasodilation and vasoconstriction; Deliver blood to capillaries.
  2. b Kidney release of renin generates angiotensis II, which causes vasoconstriction. Increase BP.
  3. c Lowest level of arterial pressure.
  4. d Pressure exerted on arterial walls during ventricular contraction.
  5. e EX - Histamine - vasodilator, decreases BP.

5 Multiple choice questions

  1. Low blood pressure, systolic pressure below 100 mg Hg. Often associated with long life and lack of cardiovascular illness.
  2. 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.
  3. Peripheral Resistance (R). - If R increases, blood flow decreases.
  4. The longer the vessel, the greater the resistance encountered.
  5. Microscopic blood vessels, walls of thin tunica intima, one cell thick. Size only allows one RBC at a time; Permit exchange of nutrients and wastes between blood and interstitial fluid.

5 True/False questions

  1. factors that remain relatively constant in vascular resistanceRespiratory pump, muscular pump and vasconstriction of veins under sympathetic control.


  2. Diastolic PressureFirst sound heart measuring blood pressure, normally 110 - 140 mm Hg.


  3. When is Angiogenesis common in the heart?In the Aorta.


  4. Vital SignsFormed when venules converge; Composed of three tunics; Return blood to the heart, facilitated by valves in veins and in limbs.


  5. Vascular resistanceThe friction between blood and blood vessel walls.
