Improvement of respiratory system

Breathing is the foundation of life. The human respiratory system includes: nasal cavity, nasopharynx, respiratory sinuses of the skull, bronchi, and most importantly the lungs. With today's environmental situation, the entire complex hourly, every minute is exposed to the strongest negative impact. The set of organs entering the respiratory system performs several functions at once. It gives us the gases necessary for the operation of all organs and systems, and helps to remove unnecessary volatile compounds, for example carbon dioxide, poisonous nitrogen. Great importance for maintaining the consistency of the physical and chemical properties of the internal environment of the body is the release through the lungs of water vapor and a number of substances that have entered the body, for example, alcohol, iodine. Therefore, the respiratory system can be called part of the excretory system.

FEATURES OF THE

RESPIRATORY SYSTEM There are so-called external and internal respiration. Internal refers to the transition of oxygen from the blood to all tissues of the body, the participation of oxygen in the oxidative processes occurring in the tissues, and the movement of one of the main products of oxidation( carbon dioxide) in the opposite direction. However, when it comes to diseases of the respiratory system, it means external respiration, the main organ of which is the lungs. Diseases can affect the individual structures of the lungs( alveoli, bronchi, pleura), but often involve various tissues. Among the most common lung diseases are called colds;it is caused by viruses or microbes. Spring-autumn outbreaks of colds are facilitated by the fact that they are transmitted from a sick person to a healthy airborne droplet( when coughing and sneezing).Many pathogens of colds permanently inhabit the mucous membranes of the nose, nasopharynx, trachea and bronchi, without showing activity. Very often the disease begins with inflammation of the nasal mucosa, and then spreads to the larynx( pharyngitis), trachea( tracheitis), bronchi( bronchitis), and sometimes to the lungs, causing their inflammation - pneumonia. Colds, not dangerous in themselves, can cause serious complications. Moreover, some people are prone to recurrent colds. This can cause a number of so-called infectious-allergic diseases - bronchial asthma, inflammation of the joints( arthritis, etc.).

Acute inflammation of the bronchial mucosa - acute bronchitis in the vast majority of cases

results in complete recovery, but sometimes acquires a chronic course. Bronchial asthma, most doctors do not consider as a single disease, considering it a pathological condition that complicates the course of many other diseases and has several forms - allergic, toxic, genetic. Inflammation of the lungs( pneumonia) is a disease that in the vast majority of cases is caused by microbes and viruses, although pneumonia is extremely rare, in which it is not possible to detect the pathogen. Pneumonia refers to widespread diseases. Their frequency, especially in industrial regions, is constantly increasing, which is most likely due to the increasing pollution of the atmosphere and a massive decrease in immunity.
