The Respiratory System

Introduction

          The Respiratory System (called also respiratory apparatus, ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment.

           In air-breathing vertebrates like human beings, respiration takes place in the respiratory organs called lungs. The passage of air into the lungs to supply the body with oxygen is known as inhalation, and the passage of air out of the lungs to expel carbon dioxide is known as exhalation; this process is collectively called breathing or ventilation. In humans and other mammals, the anatomical features of the respiratory system include trachea, bronchi,bronchioles, lungs, and diaphragm. Molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous external environment and the blood. This exchange process occurs in the alveoli (air sacs) in the lungs.

Conclusion

Humans can survive for weeks or even months without food, and days without water, but only a few minutes without breathing. Since oxygen is so vital to the energy needs of the human body, it is essential that we maintain healthy lungs by breathing unpolluted air as much as possible and by supplying the body in general with good nutrition.

Since the respiratory system is also a system of elimination, it is greatly affected when the other systems of elimination are not functioning properly. Cleansing for all the channels of elimination is an essential first step for most respiratory problems. After cleansing, the beneficial flora of the body must be reestablished to reduce or eliminate overgrowth of yeast and fungus, a very common contributor to respiratory problems of all types.

A respiratory problem can be better supported nutritionally when we establish whether the condition is "dry" or "damp," and also whether it is "hot" or "cold." Some herbs have a cooling effect, while others have a warming effect. Likewise some herbs have a drying effect while others have a soothing and moisturizing effect. With this knowledge, we can select the most appropriate nutritional aid for the individual involved.
