State
Baroreceptors in major vessels detect blood pressure changes and signal the brainstem to adjust heart rate and vessel diameter, working alongside the hormonal pathway, per Bio 2937.
Show
A sudden pressure drop triggers baroreceptor signaling that raises heart rate within seconds.
Watch for
The baroreceptor reflex acts on a seconds-to-minutes scale, while the hormonal pathway, per Bio 2937, sustains pressure longer.
