What is the most common cardiovascular disease? - CORRECT
| | | | | | | | |



ANSWER✔✔-hypertension


Approximately what percentage of Canadian adults are diagnosed with
| | | | | | | | |



hypertension? - CORRECT ANSWER✔✔-23%
| | |




List 4 potential causes of hypertension - CORRECT ANSWER✔✔-▪
| | | | | | | | |



genetic factors |




▪ environmental factors
| |




▪ psychological stress
| |




▪ diet
|




List 4 physiological consequences of untreated hypertension - CORRECT
| | | | | | | | |



ANSWER✔✔-▪ damage to blood vessels
| | | |




▪ renal failure
| |




▪ coronary disease
| |




▪ stroke
|

,What is the relationship between cardiac output, blood pressure, and
| | | | | | | | | |



peripheral vascular resistance? - CORRECT ANSWER✔✔-BP = CO x PVR
| | | | | | | | |




State which aspect of blood pressure control each of the following is
| | | | | | | | | | | |



responsible for: |




a) arterioles
|




b) venules
|




c) heart
|




d) kidney - CORRECT ANSWER✔✔-a) arterioles - *resistance*
| | | | | | |




b) venules - *capacitance*
| | |




c) heart - *rate/cardiac output*
| | | |




d) kidney - *blood volume*
| | | |




T/F: "Hypertensive individuals have different blood pressure control
| | | | | | | |



mechanisms than normotensive individuals." - CORRECT ANSWER✔✔-
| | | | | |



False. |




Both hypertensive and normotensive individuals have the same
| | | | | | | |



mechanisms of BP control, but different set points
| | | | | | |




What are baroreceptors? What is their role in controlling blood
| | | | | | | | | |



pressure? - CORRECT ANSWER✔✔-- They are mechanoreceptors
| | | | | | |



located in the carotid artery and aorta
| | | | | |

,- They sense pressure changes in blood vessels (respond to change in
| | | | | | | | | | | |



the tension of the arterial wall)
| | | | |




- The baroreflex mechanism is a fast response to changes in blood
| | | | | | | | | | | |



pressure.


Increased blood vessel stretch leads to:
| | | | |




a) baroreceptor stimulation -> ⬇SNS activity
| | | | |




b) baroreceptor stimulation -> ⬇PSNS activity
| | | | |




c) baroreceptor stimulation -> ⬆SNS activity
| | | | |




d) ⬇ baroreceptor activity -> ⬆SNS activity
| | | | | |




e) ⬇ baroreceptor activity -> ⬆PSNS activity - CORRECT ANSWER✔✔-
| | | | | | | | |



a) baroreceptor stimulation -> ⬇SNS activity
| | | | |




Decreased blood vessel stretch leads to:
| | | | |




a) baroreceptor stimulation -> ⬇SNS activity
| | | | |




b) baroreceptor stimulation -> ⬇PSNS activity
| | | | |




c) baroreceptor stimulation -> ⬆SNS activity
| | | | |




d) ⬇ baroreceptor activity -> ⬆SNS activity
| | | | | |




e) ⬇ baroreceptor activity -> ⬆PSNS activity - CORRECT ANSWER✔✔-
| | | | | | | | |



d) ⬇ baroreceptor activity -> ⬆SNS activity
| | | | | |

, Which organ is responsible for long-term blood pressure control via
| | | | | | | | | |



controlling blood volume? - CORRECT ANSWER✔✔-Kidney
| | | | |




Where is renin released? - CORRECT ANSWER✔✔-Kidneys
| | | | | |




What stimulates the kidneys to release renin? - CORRECT ANSWER✔✔-
| | | | | | | | |



⬇ BP in renal arterioles
| | | |




&
SNS activation of β1
| | |




Renin stimulates:
|




a) the conversion of angiotensinogen --> angiotensin I
| | | | | | |




b) the conversion of angiotensin I --> angiotensin II
| | | | | | | |




c) secretion of aldosterone
| | |




d) vasoconstriction of arterioles
| | |




e) 2 of the above - CORRECT ANSWER✔✔-a) the conversion of
| | | | | | | | | | |



angiotensinogen --> angiotensin I | | |




List two ways angiotensin II contributes to blood pressure control -
| | | | | | | | | | |



CORRECT ANSWER✔✔-◽ vasoconstriction of arterioles
| | | |




◽ stimulates secretion of aldosterone
| | | |
