Question

Quizplus · Accepted Answer

The carotid sinus reflex results in a decrease in blood pressure. When the carotid sinus, located in the carotid artery in the neck, is stimulated by increased pressure, it sends a signal to the brain to decrease heart rate and dilate blood vessels, thus lowering blood pressure.

Answer: D
 The carotid sinus reflex can also lead to a decrease in respiration rate, as the signal sent to the brain may affect the respiratory centers. Therefore, both choice B (decrease in blood pressure) and choice D (decrease in blood pressure and respiration rate) could be considered correct answers.
