What is the role of baroreceptors in regulating arterial blood pressure?
They have no role in regulating arterial blood pressure
They cause an increase in arterial blood pressure
They help to maintain homeostasis by signaling the cardiovascular system to adjust heart rate and blood vessel diameter in order to regulate arterial blood pressure.
They only regulate heart rate but not blood vessel diameter
Describe the mechanism of action of the baroreceptor reflex in response to changes in blood pressure.
The baroreceptor reflex only affects the kidneys, not the brain and heart
The baroreceptor reflex responds to changes in temperature, not blood pressure
The baroreceptor reflex detects changes in blood pressure and sends signals to the brain and heart to regulate it.
The baroreceptor reflex has no role in regulating blood pressure
