Chapter 20, Problem 7DYB
Summary Introduction
Introduction:
The circulation of local blood flow throughout the body depends on the total flow of blood. Total blood flow is defined as the amount of blood flowing throughout the body or in entire blood vessels in a given period of time. The total blood flow expressed in terms of liter per minute.
