  1. Blood Vessel Length
  2. Nitric Oxide
  3. factors that remain relatively constant in vascular resistance
  4. Pulse
  5. Where are Capillaries found?
  1. a Blood viscosity, and blood vessel length.
  2. b The longer the vessel, the greater the resistance encountered.
  3. c In all tissues except for cartilage, epithelia, cornea and lens of eye.
  4. d NO - is a brief but potent vasodilator. Decrease BP.
  5. e Pressure wave caused by the expansion and recoil of elastic arteries. Varies with health, body position, and activity.

5 Multiple choice questions

  1. The stickiness of the blood due to formed elements and plasma proteins.
  2. Blood viscosity, total blood vessel length, blood vessel diameter.
  3. Smooth muscle and elastic fiber layer, regulated by sympathetic nervous system.
  4. First sound heart measuring blood pressure, normally 110 - 140 mm Hg.
  5. Reflects two factors of the arteries close to the heart. The elasticity (compliance or distensibility), and the amount of blood forced into them at any given time.

5 True/False questions

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


  2. Fenestrated CapillariesHave large fenstrations and intercellular clefts for the greatest permeability, even allowing passage of blood cells.


  3. Vascular (venous) sinuses?Specialized, flattened veins with extremely thin walls (e.g., coronary sinus of the heart dural sinuses of the brain).


  4. What is directly proportional to Blood Flow (F)?Blood hydrostatic pressure gradient. - If P increases, BF speeds up.


  5. Inflammatory ChemicalEX - Histamine - vasodilator, decreases BP.
