Question
Chapter 32, Problem 3RQ
Summary Introduction
To determine:
The positive feedback mechanism with one physiological example.
Introduction:
Every organism body performs several chemical and physiological processes, throughout their body. These processes require optimum conditions for efficient working. These conditions are auto regulated by the body, by a process known as homeostasis. Feedback mechanism is one of the l mechanisms involved in “homeostasis”.
Summary Introduction
To determine:
The reason why positive feedback is rare in the physiological processes.
Introduction:
Feedback mechanism is of two types: negative feedback and positive feedback. Negative feedback slows down the production rate and positive feedback accelerates the production rate.
