Lung

The lungs are two organs filled with air, one located on the right side of the chest, and the second on the left side of it, and the air reaches the lungs through the trachea, which connects to the lungs through the bronchi. In fact, the bronchi divide into bronchioles that end in small sacs known as alveoli , and between the alveoli there is a thin layer of cells rich in blood vessels Known as the interstitium layer, this layer supports the alveoli to be able to perform its function in providing the blood with oxygen, and to get rid of the carbon dioxide that is transported to it from the cells of the body through the blood, and it is worth noting that the lungs are covered with a layer of fluid that acts as a lubricant. Lubricant: to prevent friction, and to allow the lungs to expand and narrow according to their air content.

lung diseases

The lung may be exposed to many diseases, and it may be difficult to count these diseases, including the following:

Chronic bronchitis: Chronic bronchitis is defined as an irritation and inflammation of the bronchi, which leads to the formation of thick mucus in them, and makes the entry of air into the lungs difficult, and it is chronic due to the persistence of the condition for more than three months, and it is attributed Most cases to smoking; Smoking irritates the bronchi.
Pulmonary emphysema: can be summarized as pulmonary emphysema that the weakness of the alveoli and damage due to smoking often, and the consequent lack of oxygen reaching the blood, it should be noted that this disease chronic and can not be cured, but give the medicine is intended to reduce the speed of Disease progression and control of its symptoms.
Chronic obstructive pulmonary disease (Chronic Obstructive Pulmonary Disease) is a disease that affects the lung and causes a person to suffer from difficulty breathing, and most of those affected are smokers.
Pneumonia: Pneumonia often occurs as a result of infection , and this infection may be bacterial, viral, or fungal, and although anyone may develop pneumonia. However, the elderly and people with a weak immune system are more likely to develop it.
Asthma happens asthma as a result of narrowing of the airway and inflammation, causing the suffering of the injured chest pain, shortness of breath, a cough that occurs mostly in the early morning or at night, with an estimated infected rate of asthma in the United States nearly 25 million It is considered a chronic lung disease.
Respiratory failure resulting from obesity syndrome: deficiency syndrome show breathing caused by obesity in some people who suffer from obesity , causing disability breathing, and it accumulates carbon dioxide in the blood, less oxygen level.
Pulmonary fibrosis: known as pulmonary fibrosis that increased pulmonary tissue thickness and hardening, which leads to increased risk of lung infections and other complications such as cancer .
Grananism or sarcoidosis: Sarcoidosis appears in the form of inflammatory cells in the skin, eyes, lungs, and lymph glands often, and many scientists attribute this disease to the body's immune system attacking the body incorrectly after inhaling a foreign substance from the air. Women are more susceptible to infection, in addition to it most often appears in the age period ranging between 20-40 years.
Pleural effusion or pleural effusion: A pleural effusion is known to the general public as the accumulation of water on the lungs, and in this case, fluid accumulation occurs in the area separating the lungs from the chest cavity , and a person may develop this The disease is the result of infection, or as a complication of some diseases such as kidney and liver disease, congestive heart disease, and pulmonary embolism, and it is also likely to occur in cases of a person suffering from an autoimmune disease such as lupus and rheumatoid arthritis .
Bronchiectasis: Bronchiectasis expands as a result of frequent infection, and what the patient complains of most often is a persistent cough accompanied by a large amount of phlegm.
Cystic Fibrosis: Cystic Fibrosis occurs as a result of the accumulation of mucus in a way that the body cannot get rid of as in the normal situation, and it results in the patient having repeated pneumonia and bronchitis, and it is worth noting that this disease has a genetic origin.
Pulmonary tuberculosis: The pulmonary tuberculosis known as tuberculosis occurs as a result of infection with the bacteria known as Mycobacterium tuberculosis or Koch's bacillus (scientific name: Mycobacterium tuberculosis).
Acute respiratory distress syndrome: occurs in acute respiratory distress syndrome the accumulation of fluid in the alveoli, thereby reducing the capacity and efficiency of the lungs need to take the body of oxygen.
Pulmonary embolism: pulmonary embolism as a result of the transmission of a blood clot from the leg often to the lungs after arriving to the heart. Lung cancer may affect lung cancer any part of it, and is often caused by smoking.
Pulmonary hypertension: Pulmonary hypertension is defined as high blood pressure in the arteries that carry blood from the heart to the lungs, and the cause of this rise may not be known.
Influenza: Influenza occurs as a result of exposure of the body to one of the viruses that cause it, and as a result the person suffers from a fever and cough, and its effect may be life-threatening in the elderly who suffer from other diseases.

Symptoms of lung disease

Symptoms that appear on people with a lung disease vary according to the type of disease, but there are some general symptoms and signs that may appear in most diseases, including the following:
