Question

1. Systolic blood pressure in arteries is always lower than the diastolic pressure.
   1. True
   2. False
2. Increased end diastolic volume will affect;
   1. heart rate
   2. mean arterial pressure
   3. total peripheral resistance
   4. stroke volume
3. As blood traveling from the heart passes through numerous increasingly smaller vessels, the blood pressure:
4. 1. Decreases
   2. does not change
   3. remains constant
   4. Increases
5. blood flow from the right ventricle to the lungs and back to the left atrium is called
   1. systemic circulation
   2. coronary circulation
   3. pulmonary circulation
   4. fetal circulation
6. Blood pressure is highest in the
   1. Arterioles
   2. Veins
   3. Venules
   4. Arteries
7. Epinephrine would
   1. decrease heart rate
   2. increase cardiac output
   3. decrease cardiac output
   4. cause no change.
8. The pulse wave is created by:
   1. The electrical signals of the heart
   2. The contraction of the arteries
   3. The contraction of the left ventricle
   4. The contraction of the bronchioles
9. If the arteries are vasodilated, then the pulse amplitude will be:
   1. Faster
   2. Slower
   3. Higher
   4. Lower
10. A decrease in blood pressure will cause:
    1. An increase in the parasympathetic system
    2. Vasoconstriction
    3. Vasodilation
    4. Decreased heart rate

Answer 1

1. False

• Systolic BP - 120 mm Hg and Diastolic BP - 80 mm Hg

2. Stroke volume

• Stroke volume = End Diastolic volume - end systolic volume

3. Decreases

4. Pulmonary circulation

5. Arteries

6. Increase cardiac output

• Epinephrine is released from sympathetic nerves. It increases cardiac contractility, heart rate and cardiac output.

7. Contraction of arteries

8. Lower

9. Vasoconstriction
