Question

When the blood pressure goes down, what happens to the heart rate?

1) It goes up
2) It goes down
3) It stays the same
4) It cannot be determined

Answer 1

When blood pressure goes down, the heart rate can increase due to a decrease in baroreceptor firing, which triggers sympathetic stimulation of the heart.

Step-by-step explanation:

When blood pressure goes down, the heart rate can increase. This is because when blood pressure drops too low, the rate of baroreceptor firing decreases. This triggers an increase in sympathetic stimulation of the heart, causing the heart rate to increase.
