Expert Solution
Step 1

 Peripheral resistance can be defined as the resistance applied by the blood vessels for the flow of blood and also for generating the blood pressure. It is generally measured by R (Reynold’s number), which can be obtained by dividing the pressure in mm Hg by flow in ml/sec.
