Respiratory System Diseases

Respiratory system diseases are one of the major causes of death all over the world. Any complication caused in the components of the lung organ can lead to these ailments. While genetic and environmental factors do play an important role in the development of these diseases, bad habits like smoking is one of the worst acquired cause all over the world. Unfortunately, death caused by respiratory diseases is very dreadful and it is hard for the family members of the suffer to see such a painful end of life of their loved one.

Some of the Important Types of Respiratory System Ailments are:
Obstructive Lung Disease: Here the airways of the lung become small in volume. Then, it becomes difficult for the air to come in and get out of the lung resulting in obstruction for the patient to breath freely. Examples are bronchiectasis and bronchitis.

Inflammatory Lung Disease: There are tiny air sacs in the lungs which act as filters. They are separated from each other by surrounding tissues known as the interstitium. Any swelling in these tissues causes a host of lung ailments known as the Inflammatory lung diseases. Examples are asthma and Chronic Obstructive Pulmonary Disease.

Restrictive Lung Disease: Here the lung volume reduces leading to a decrease in the total lung capacity (less than 80 percent) and inadequate ventilation. Here the covering of the lung technically called the parenchyma and the connective tissues of the air sacs are damaged leading to the mentioned consequences. Though there are 100 known diseases of this category, in 70 percent cases, the cause is unknown.

Respiratory Tract Infection: The respiratory tract is the piping system through which air enters the lungs and leaves out of our system. It can be divided into two systems, namely the upper and lower respiratory tracts. These sections are prone to infections. All infections in the upper tract like cold are less serious compared to the infections in the lower respiratory tract like pneumonia.

Malignant Tumor: Lung cancer comprises 15 percent of all cancers diagnosed every year. It is responsible for 29 percent of cancer related deaths. Noncancerous benign tumors rarely cause respiratory diseases.

Neonatal Disease: It is a class of disease that affects the newborns. One such ailment is pulmonary hyperplasia. It further leads to conditions like acute respiratory distress syndrome and pulmonary hyper tension.

Pulmonary Vascular Disease: Pulmonary circulation system involves intake of oxygen-depleted blood from the heart and sending oxygen rich blood back to the heart from the lung. Any ailment associated with the disruption of this system is known as the pulmonary vascular disease.

Pleural Cavity Disease: The pleura is a large sheet of tissues that surrounds the chest cavity. In between two such sheets there is a fluid which serves as a lubricant. Any infection, excess build up of fluids, formation of tumors and the presence of blood or air in this cavity cause pleural cavity disease.

Conclusion: Some of these above mentioned types of lung ailments can be diagnosed and treated easily owing to the understanding of their origin. Research is underway to gain a better.
