Summary Introduction

To discuss:

The CO₂ loading in the systemic tissues that influences the unloading of O2; the meaning of the utilization coefficient, and the normal resting value.

Introduction:

The respiratory involves in the exchange of gases such as oxygen (O₂) to the tissues in the body and to remove carbon dioxide (CO₂) from the tissues. Oxygen is taken up by inhalation, which reaches the systemic tissues for metabolic processes. Similarly, CO₂ produced during the metabolic processes in the tissues are eliminated by the lungs by the process of exhalation. The systemic gas exchange involves the unloading of O₂ and loading of CO₂ to the blood capillaries.
