What is Bronchitis Asthmatic - Pollution: Checking the Damages Caused to the Respiratory System

---

THE RESPIRATORY SYSTEM DAMAGE  The long-term effects of air pollution include serious diseases like cancer. The highly polluted city air slowly metamorphoses our healthy and pink colored lung tissues into darkened particles of smog, dust, and other pollutants, making the lungs more vulnerable to infection. The highly sensitive respiratory system can be damaged in a number of ways.

Tuberculosis: Also Known as TB, It is Caused by the Tuberculosis Bacterium

---

The lungs are primarily attacked in TB. At times, other body tissues also get affected. Unaddressed, the lung infection can even destroy the lung tissues. Earlier, tuberculosis was controlled by antibiotics. However, the bacterium has evolved an antibiotic-resistant strain posing a grave health problem.

Common cold, running nose & stuffy nose: Viruses cause colds by targeting the pharynx and the nasal passages. First, the viruses infiltrate the body through the respiratory system. Then, they target the cells in the nasal passage membranes. But before they can destroy the cells, the body's immune system fights back. The immune system increases the flow of blood to the area. Such reinforcement of white blood cells leads to swelling of the membranes. This causes the stuffy nose. Increase in mucous secretions to neutralize the viral attack leads to the runny nose. Mentionably, the infection can affect the sinuses -- membrane-lined cavities located within the head, besides the middle ear and the lower respiratory tract. The sources used for the information for this article on Bronchitis are all dependable ones. This is so that there be no confusion in the authenticity of the article.

These Substances Settle Down in the Lungs' Mucous Layers

It takes almost an hour for the paralyzed cilia to recover. But repeated paralyzing from the heated tar eventually kills them. Mucus builds up as a result of repeated smoking. The accumulated mucus blocks the smaller air passages. The obstruction triggers the 'smoker's cough'. This familiar reflex cough is the distressed lung's effort to clear the air routes.

• ARDS: Adult Respiratory Distress Syndrome (ARDS) occurs when the lungs get severely injured.
• Many automobile accidents, poisonous gases, or lung inflammation can cause such a dysfunction.
• ARDS patients generally have to battle for life with 50 per cent survival rate.
• It was with great relief we ended writing on Bronchitis.
• There was just too much information to write, that we were starting to lose hopes on it's completion!

Lung Cancer: the Main Cancer Causing Agents are Uranium, Asbestos, and Tobacco Smoke

Genetic reasons can also cause cancer. The respiratory cancerous tumors are formed in the lung tissue (alveolar), the bronchioles or the bronchi. Early detection of such tumors can halt their progression to other parts of the body. Then the treatments are more effective, and the prognosis for recovery is rather good. Unfortunately, 85 per cent of the lung cancers are diagnosed at a later stage when the tumors have already spread. In such extreme cases, the prognosis is poor. We have also translated parts of this composition into French and Spanish to facilitate easier understanding of Bronchitis. In this way, more people will get to understand the composition.

Hay Fever & Asthma: These are Allergic Reactions of the Respiratory System

---

These conditions are caused when the immune system is irritated by irritants like dust or pollen. The symptoms of hay fever are sneezing, watery eyes, and runny nose. It is a seasonal reaction when there is abundance of pollens in the air. Asthma attacks are generally mild. But, they can be life threatening too. A person suffering from asthma experiences difficulty in breathing. It occurs as the bronchi and bronchioles get inflamed and remain constricted temporarily.
