Question
Chapter 27.5, Problem 3MC
Summary Introduction
To determine:
The reason for considering the regulation of blood pressure as negative feedback.
Introduction:
The pressure which is exerted by blood on the walls of arteries is known as blood pressure. The blood pressure is regulated to provide sufficient and required amount of blood to various regions of the body. Any disbalance in the blood pressure can generate a series of stimulus or response to maintain it.
