Chapter 25.2, Problem 7R

A.

Summary Introduction

To determine: The three major buffer systems of the body.

Introduction: The binding of the buffer system can take place with hydrogen ions, and these systems are important for balancing acid-base concentration temporarily. Buffer systems can present in ICF, or in ECF, or it can be present in both the fluid compartments.

B.

Summary Introduction

To determine: The fluids that are buffered by the phosphate buffer systems.  

Introduction: The primary function of the buffer system is to delay the pH shift in the fluid compartment. However, they cannot prevent the pH shift. Thus, an acid-base imbalance can temporarily be solved by a buffer system.
