The baroreceptor reflex would cause which of the following events to occur if the reflex was caused by an increase in blood pressure?
A) Increased parasympathetic stimulation of the heart
B) Increased heart rate
C) Increased cardiac output
D) Increased force of contraction
E) Increased sympathetic stimulation of the heart
Baroreceptor Reflex
A reflex mechanism that helps maintain blood pressure stability by adjusting heart rate and blood vessel diameter in response to changes in blood pressure.
Blood Pressure
The force exerted by circulating blood on the walls of blood vessels, a critical indicator of cardiovascular health.

Final Answer :
A
Explanation :
The baroreceptor reflex responds to changes in blood pressure. If blood pressure increases, the reflex acts to decrease it by increasing parasympathetic stimulation of the heart. This leads to a decrease in heart rate, not an increase, thereby helping to lower blood pressure back to normal levels.
