  1. Name the 2 short-term regulations of Blood Pressure ?
    • 1.Neural Mechanism
    • 2.Humoral Mechanism
  2. Which nerve sends impulses to heart through the parasympathetic system ?
    The Vagus Nerve in cardiovascular center
  3. How does the sympathetic transmit impulses to the heart ?
    Through the spinal cord and peripheral sympathetic nerves
  4. Intrinsic Circulatory Reflexes
    • -ANS controlled
    • -Includes baroreceptors and chemoreceptors
    • -Used for rapid and short term blood pressure control
  5. Extrinsic Circulatory Reflexes
    • -Found outside the circulation
    • -Mediate response such a pain and cold
  6. What are the two main mechanism the Humoral mechanism relies on ?
    • 1. Renin-Angiotensin-Aldosterone system
    • 2.Vasopressin
  7. How does the Renin-Angiotesin-Aldosterone system increase blood pressure ?
    • -Decrease in ECM + Arterial Blood Pressure
    • - Renin is released from the Juxtaglomerular cells
    • -Travels in blood and converts into Angiotensin
    • -Converts into Angiotensin I¬†
    • - enters lungs and catalyzed by Angiotensin-Converting Enzyme
    • -Converts in Angiotensin II
  8. How does Vasopressin regulate BP ?
    • -Decrease Blood volume + Blood Pressure
    • -Release from Posterior Pituitary gland
    • -Direct vasoconstrictor effect
    • -Increases water retention
  9. What does Hypertension represent ?
    An elevation in systolic and /or diastolic blood pressure
  10. True or False
    Men are at greater risk of Hypertension then women.
    TRUE
  11. What is primary  hypertension ?
    Chronic elevation of BP occurs w/o evidence of other disease condition .
  12. Name 3 risk Factors for Primary HP
    • Family History
    • Race
    • Age
    • Diabetes
    • High salt intake
    • Obesity
    • Excessive Water intake
  13. What is secondary hypertension ?
    Elevation of BP results from some other disorder.
