Describe how an increase in blood pressure is returned to normal using the baroreceptor reflex
What will be an ideal response?
The baroreceptor reflex is a negative feedback loop that responds to an increase in blood pressure. When blood pressure increases, parasympathetic neurons in the medulla inhibit sympathetic activity, inducing vasodilation and decreased heart rate, lowering cardiac output. Note that the parasympathetic neurons have no direct effect on most blood vessels.
