Question
Chapter 49.5, Problem 1R
Summary Introduction
To review:
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.

Why do positive feedback systems that are part of a normal physiological response include some mechanism that terminates the system?
What if the SHH you are making needs to be accumulated in the cell so that it can be released all at once into the extracellular space at a specific time? How would you store the produced SHH? What would need to occur to release all of the SHH from storage into the extracellular space?
What condition is shown in the diagram? Explain how the body regulate this process.
