Arrange the events in the correct order to describe the response to a fall in blood pressure.
Understand the Problem
The question is asking to arrange a series of physiological responses in the correct order following a fall in blood pressure, using the provided descriptions.
Answer
Event 1: Output from arterial baroreceptors falls Event 2: Input to cardiovascular centre is diminished Event 3: Sympathetic output from cardiovascular centre rises Event 4: Heart rate increases Event 5: Cardiac output rises Event 6: Systemic blood pressure rises
The final answer is: Event 1: Output from arterial baroreceptors falls Event 2: Input to cardiovascular centre is diminished Event 3: Sympathetic output from cardiovascular centre rises Event 4: Heart rate increases Event 5: Cardiac output rises Event 6: Systemic blood pressure rises
Answer for screen readers
The final answer is: Event 1: Output from arterial baroreceptors falls Event 2: Input to cardiovascular centre is diminished Event 3: Sympathetic output from cardiovascular centre rises Event 4: Heart rate increases Event 5: Cardiac output rises Event 6: Systemic blood pressure rises
More Information
The sequence describes the body's baroreceptor reflex in response to a drop in blood pressure, where decreased baroreceptor activity increases sympathetic nerve activity to restore blood pressure.
Tips
A common mistake is to confuse the sequence of neural activity and physiological responses. Focus on the order of detection and response.
