1
Q
Where are baroreceptors found?
A
Carotid arteries in neck and aorta
2
Q
How is blood pressure controlled by baroreceptors during exercise?
A
Blood vessels dilate in response to adrenaline causing blood pressure to fall.
This reduces the stretch on baroreceptors.
Cardiac control centre sends signals along the sympathetic nerve to stimulate heart rate and increase blood pressure by vasoconstriction.
