THE RESPIRATORY TRACT
The respiratory tract is an anatomical structure primarily devoted to breathing and made up of several organs with the function of channeling air from the external environment, rich in oxygen, towards the inner part of the body, eliminating at the same time air “already breathed”, which is therefore rich in carbon dioxide.
During inhalation the first organs that air comes in contact with are the nose and the oral cavity, and right afterwards the pharynx. The passage of air in the upper airway (how this set of organs is called) allows it to be warmed up and take on water vapor: this way it is ready to move on to the second part of the respiratory tract, i.e. at mid-level. Larynx and trachea channel inhaled air towards the bronchi, bronchioles and the lung alveoli, i.e. the lower airway, or final part of the respiratory tract. It is in this anatomical area that gaseous exchanges of oxygen and carbon dioxide take place, which are at the basis of the respiratory process.
The respiratory tract is anatomically closely connected to the set of thoracic muscles and to the diaphragm, which enable the rib cage to expand during inhalation. Apart from the main, essential respiratory function, the respiratory tract also has another function: maintaining the right balance of acidity in the blood by regulating the quantity of carbon dioxide circulating.
All organs part of the respiratory tract are particularly exposed to attacks by bacteria, viruses or other harmful elements: in fact, these can be present in air inhaled and therefore come into direct contact with the mucosa of the nose, oral cavity, pharynx, etc. When the mucosa of the organs involved is not prepared to respond to the pathogenic attack, a whole series of disorders can develop, ranging from colds, pharyngitis, laryngitis, up to bronchitis, pneumonia, tuberculosis and asthma which easily tend to become chronic if not adequately treated – particularly in the case of pharyngitis, tracheitis, bronchitis,.
It is therefore essential to be able to resort to adequate remedies which, while respecting the physiology of the mucosa, may effectively guarantee a definitive solution and at the same time reduce the risk of relapses and chronicity.
