Question

Chapter 30, Problem 12WIO

Summary Introduction

To determine:

What change in blood vessel diameter would raise blood pressure.

Concept introduction:

Blood pressure is defined as the pressure exerted by blood on the walls of blood vessels. It is observed by measuring contraction and relaxation of heart. Contraction of heart is called systole while relaxation is called diastole. A normal blood pressure is 80120 such as systole /diastole.
