Lung disorders affect the respiratory system, including bronchitis, asthma, flu, alveolitis, and emphysema. These ailments can be caused by pollution, viruses, or allergies, and can lead to shortness of breath, wheezing, and coughing. Some lung disorders, like the flu, can mutate, making it difficult to develop immunity.
Lung disorders are diseases and infections that occur in the respiratory system, also known as the respiratory tract. There are various ailments that affect various parts of the respiratory tract. For example, bronchitis is a disorder that affects the bronchial tubes. Asthma, on the other hand, is a disease that infects the lungs.
One of the most frequent lung disorders is the flu, properly called the flu. This is a viral infection that occurs when a person breathes in some kind of virus. This usually happens when a person is exposed to infected droplets from another person’s sneeze or cough. Influenza is often defined in a way that might lead a person to believe that there is only one kind. In reality, the flu can be caused by hundreds of different viruses.
The flu can be complicated because these lung disorders have the ability to mutate. This means that a person can develop immunity to the strain currently in their body, but can transform into a new strain. When this happens he can get sick again and become a threat to people he has already infected once.
Asthma is a lung disease characterized by shortness of breath, wheezing and coughing. Asthma attacks occur when the bronchioles contract and excess mucus inhibits airflow. Bronchioles are small passageways that act as a network to supply air to all of the human lungs. In a healthy person, the bronchioles expand during inhalation to improve airflow. With a person with asthma, triggers such as animal fur or pollen cause the bronchioles to become inflamed when they should be expanding, resulting in excessive mucus.
Bronchitis is an infection that involves inflammation of the larger airways to the lungs, known as the bronchi. These lung ailments are usually caused when a person inhales too much pollution. People who smoke cigarettes often suffer from these lung ailments because the filtering system of the mucous membranes in the bronchial tubes becomes irritated by excessive pollutants.
The alveoli are tiny sacs of air contained in the lungs. They contribute to the elasticity of the lungs, which facilitate the transfer of oxygen to the blood. One of the lung disorders that affect them is known as alveolitis. The cause of such ailments is usually an allergic reaction to inhaled plant or animal matter.
Another of the lung disorders that affects the alveoli is emphysema. This disease is caused by the destruction of the alveoli. This results in less area for oxygen exchange. At first, there may be no signs of this disease. Eventually, however, shortness of breath can develop and the damage can spread to the lungs.
