  1. a Endothelial layer that lines the lumen of all vessels.
  2. b (ADH)-(Vasopressin) - Causes intense vasoconstriction in cases of extremely low BP. Increases BP.
  3. c NO - is a brief but potent vasodilator. Decrease BP.
  4. d Blood flow caused by the pumping action of the heart, pressure results when flow is opposed by resistance.
