Respiratory systemSystem, from Latin systema, it’s a ordered module of interrelated and interacting elements. The notion can refer to both real (material) objects and abstract (symbolic) concepts that are endowed with organization.

Respiratory, for its part, is that which serves for the breathing or that facilitates this physiological process. It should be remembered that breathing consists of absorbing the air, take some of its substances and expel it modified. In aerobic living beings, respiration is essential for life. Humans, for example, capture oxygen as you breathe in and then breathe out carbon dioxide.

It is known as respiratory system or respiratory system to the set of organs Y muscles which is responsible for capture oxygen through inspiration and remove carbon dioxide through exhalation after the process of cellular metabolism.

In the case of humans, the respiratory system includes components such as nostrils (allowing air to enter), the pharynx (helps air reach the lower airways), the larynx (filters the inspired air), the windpipe (provides an open path to inhaled and exhaled air), the bronchi (they carry air from the trachea to the bronchioles), the bronchioles (they carry the air towards the alveoli), the alveoli (that allow the exchange gaseous), the lungs (they carry out this gas exchange with the blood) and the diaphragm (a muscle involved in breathing).

In the respiratory system of the human being can be distinguished between the driving system and the exchange system. The latter is known as the non-respiratory zone, since there is no gas exchange there.

Diseases of the respiratory system


Respiratory systemAn asthma is known as disease of the lungs of the diffuse and obstructive type characterized by the presence of coughing, wheezing (sound similar to the whistle produced when breathing) and difficulty in breathing. It is a chronic inflammatory disorder of the airways found in the lungs; As the bronchial tubes swell, their lumen becomes narrower, which generates more mucus production and facilitates the contraction of your muscle fibers.

Inflammation of the bronchi makes them especially irritable and very sensitive to certain inhalant-type substances, as well as to certain situations, and these stimuli are called triggering agents. It is worth mentioning that the bronchi can narrow in a very short time.

Among the most common symptoms of asthma are coughing (usually at night or in the early morning, but also while doing some kind of physical exercise, crying or laughing), chest tightness (which is perceived as a discomfort in the chest) and fatigue.


Bronchitis occurs when the bronchi suffer from inflammation, which can occur from a infection viral or bacterial, among other causes. It is possible to distinguish between bronchitis sharp Y chronicle, of short and long duration respectively.

Some of the symptoms of bronchitis are coughing up mucus (sometimes with blood), blocked alveoli, wheezing, and shortness of breath. In addition, this disease affects the mood and mood of those who suffer from it, which is why they usually go through a general malaise.


It is an infectious disease that affects the respiratory system and is often mistaken for a cold. normal, since they share certain symptoms, such as a sore throat, congestion and cough. However, it differs mainly by the severity of the inflammation of the airways, greater in this case, and because it requires a longer rest.

In addition to the aforementioned symptoms, lack of energy, irritation in the eyes, difficulty speaking, generalized body pain and fever (during the first days) are also noted.
