Chapter 21, Problem 5P

Summary Introduction

To describe:

The factors that control the movement of water and electrolytes from one fluid compartment to another.

Introduction:

The major factors that control the movement of water and electrolytes from one fluid compartment to another include the hydrostatic pressure and osmotic pressure. The net pressure difference moves the fluid from the plasma in the blood vessels to the interstitial fluid and vice-versa. The fluid further enters the tissues and lymphatic vessels for the exchange of ions, which maintain the concentration gradient.
