Question

Explain how baroreceptor reflexes serve as an example of homeostasis and negative feedback by describing the events that occur when homeostasis is disturbed and there is a rise in blood pressure

Answer 1

I shall draw the mechanism of baroreceptor reflex when there is a rise in blood pressure

Increase in blood pressure Stimulates baroreceptor High-intensity baroreceptor firing Increases parasympathetic activity Heart rate will now decrease Overall Cardiac output decreases Blood pressure decreases.

This is the event happening when homeostasis is disturbed by a rise in blood pressure
