Changes in which level would be sensed by baroreceptors and relayed to the vasomotor center?

Question

Quizplus · Accepted Answer

Baroreceptors are sensory receptors that detect changes in blood pressure. When blood pressure increases, baroreceptors send signals to the vasomotor center in the medulla oblongata, which then causes blood vessels to dilate and blood pressure to decrease. Conversely, when blood pressure decreases, baroreceptors send signals to the vasomotor center, which then causes blood vessels to constrict and blood pressure to increase.
