short term control of blood pressure Flashcards
1
Q
What do the baroreceptors sense and give examples
A
Increased blood pressure - the carotid sinus at the bifurcation of the internal and external carotid arteries
2
Q
What is the vasalva manouevre and what does it cause
A
Forced expiration when the mouth is closed - increased thoracic pressure which reduces filling pressure from the veins which therefore reduces MAP which should be sensed by baroreceptors to correct it
3
Q
What can be used to test the funciton of the baroreceptors
A
The vasalva manouevre
