Expert Solution

Step 1

Barrow receptor reflex is one of body's homeostasis mechanism that helps to maintain bloodpressure in nearly constant levels.

RR interval the time interval between the two successive R waves in the QRS signal in the ecg.The bloodpressure is the result of vascular resistance and cardiac output. The Barrow receptor reflex are always controls and regulating bloodpressure and heart rate.
