The reason why autoregulation in Figure 49.19 is described as a positive feedback loop. Given: The control of blood pressure through the local and systemic mechanisms has been described in figure 49.19. Introduction: Autoregulation of blood pressure means maintaining constant blood flow throughout the system by the organs themselves. In this type of regulation, if there is a fall in blood pressure of any organ, then it can be returned to its normal range within a few minutes by the organ itself. It involves both positive and negative feedback loops.
