- a First sound heart measuring blood pressure, normally 110 - 140 mm Hg.
- b Blood flow caused by the pumping action of the heart, pressure results when flow is opposed by resistance.
- c ANP - Causes blood volume and pressure to decline (produced by atria of the heart0.
- d The friction between blood and blood vessel walls.

5 True/False Questions
Hypothension → Temporary low BP and dizziness when suddenly rising from a sitting or reclining position.
Blood Vessel Length → The longer the vessel, the greater the resistance encountered.
Vasa Vasorum → Pulse and blood pressure, along with respiratory rate and body temperature.
Fenestrated Capillaries → lack pores and have a intercelluar clefts that allow only diffusion of water and small solutes.
Veins → Formed when capillary beds unite. Allow fluids and WBC's to pass from the bloodstream to tissues. Collect blood from capillaries and pass it on to veins.
