  1. factors that remain relatively constant in vascular resistance
  2. Autoregulation
  3. Vital Signs
  4. Elastic (Conducting) Arteries
  5. Hypertension
  1. a Automatic adjustment of blood flow to each tissue in proportion to its requirements at any given point in time.
  2. b Pulse and blood pressure, along with respiratory rate and body temperature.
  3. c Blood viscosity, and blood vessel length.
  4. d 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.
  5. e 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 Multiple choice questions

  1. Endothelium with sparse basal lamina.
  2. (MAP), average pressure in the arteries.
  3. Endothelial layer that lines the lumen of all vessels.
  4. ANP - Causes blood volume and pressure to decline (produced by atria of the heart0.
  5. Vessels of the vessels - larger veseels contain this. Nourish the external tissues of the blood vessel wall.

5 True/False questions

  1. Systemic Pressure in the right atrium0mm Hg.


  2. What is Blood Flow inversely proportional with?Peripheral Resistance (R). - If R increases, blood flow decreases.


  3. Diastolic PressureWhen sound disappears is recoreded, usually 70 - 80 mm Hg.


  4. AlcoholCauses BP to drop by inhibiting ADH.


  5. Blood Vessel LengthThe longer the vessel, the greater the resistance encountered.
