Respiratory system health: Prevention of lung diseases

Respiratory system health: Prevention of lung diseases

I. Anatomy and physiology of the lungs: the basis of health

A. The structure of the respiratory system:

1. Upper respiratory tract:

   a. Nose: The first barrier for inhaled air. Cleans, warms and moisturizes the air, preparing it for admission to the lower respiratory tract. The nasal shells covered with the mucous membrane increase the surface area for this processing. The blood vessels under the mucous membrane warm the air, and the mucus captures dust and other particles. Inflammation of the nasal mucosa (rhinitis) can disrupt these functions, leading to difficulty breathing and increased susceptibility to infections.

   b. Pharynx: The general part of the respiratory and digestive systems. It is divided into a nasopharynx, oropharynx and larynx. The nasopharynx is connected to the nasal cavity and the Eustachian pipe (leading to the middle ear). The oropharynx and larynx are general ways for air and food. Epiglottis, the cartilage valve, closes the entrance to the larynx during swallowing, preventing food from entering the respiratory tract. Inflammation of the pharynx (pharyngitis) can be caused by a viral or bacterial infection and is manifested by sore throat, difficulty swallowing and fever.

   c. Larynx: Contains vocal cords responsible for the formation of sound. The cartilage frame of the larynx protects the vocal cords and supports the respiratory tract open. Inflammation of the larynx (laryngitis) can lead to hoarseness, cough and difficulty breathing.

2. Lower respiratory tract:

   a. Trachea: A cartilage pipe connecting a larynx to the bronchi. The cartilage rings support the trachea open, preventing its decrease. The mucous membrane of the trachea contains ciliary epithelium, which moves mucus and captured particles up to the throat for jerking or swallowing. This is an important mechanism for purification of the respiratory tract.

   b. Bronchi: The trachea is divided into two main bronchi (right and left), which are included in the lungs. The bronchi continue to branch into all smaller bronchioles, forming a bronchial tree. The walls of the bronchi also contain cartilage rings and ciliary epithelium. Inflammation of the bronchi (bronchitis) can be acute (usually caused by a viral infection) or chronic (often associated with smoking or air pollution).

   c. Bronchioles: The smallest airways in the lungs. They do not contain cartilage and have thinner walls. Bronchioles end in alveoli. The narrowing of the bronchiol (bronchospasm) can cause difficulty breathing, as in asthma.

   d. Alveoli: Microscopic air bags where gas exchange occurs between air and blood. The lungs contain millions of alveoli, providing a huge surface area for gas exchange. The walls of the alveoli are very thin and surrounded by capillaries. Damage to the alveoli (as with emphysema) significantly reduces the effectiveness of gas exchange.

B. Breathing mechanics:

1. Inhalation (inspiration):

   a. Reducing diaphragm: The diaphragm is the main respiratory muscle. When reduced, it drops, increasing the volume of the chest cavity.

   b. Reducing intercostal muscles: External intercostal muscles raise the ribs, increasing the volume of the chest.

   c. Negative pressure: An increase in the volume of the chest cavity creates negative pressure in the lungs compared to atmospheric pressure, forcing air to enter the lungs.

2. Exhale (expiration):

   a. Relaxation of the diaphragm and intercostal muscles: The diaphragm and intercostal muscles relax, reducing the volume of the chest cavity.

   b. Increase in pressure: A decrease in the volume of the chest cavity increases the pressure in the lungs compared to atmospheric pressure, forcing air to get out of the lungs.

   c. Active exhalation: With intense physical activity or in some diseases, additional muscles (for example, abdominal muscles) for active exhalation can be used.

C. Gas exchange:

1. Alveolar-capillary gas exchange: Oxygen from inhaled air diffuses through the walls of alveoli and capillaries in the blood, where hemoglobin in red blood cells is associated with hemoglobin. Carbon dioxide from the blood diffuses in alveoli and exhales. The effectiveness of gas exchange depends on the surface area of ​​the alveoli, the thickness of the alveolar-capillary membrane and the difference in the partial pressure of oxygen and carbon dioxide.

2. Oxygen transport: Oxygen is transported by blood mainly in hemoglobin form. A small amount of oxygen is dissolved in blood plasma. Hemoglobin containing iron is able to bind four oxygen molecules.

3. Carbon dioxide transport: Carbon dioxide is transported by blood in three forms: dissolved in plasma, in the form of bicarbonate ions and in hemoglobin form (carbabeminohemoglobin).

D. Respiratory regulation:

1. Respiratory center: Located in the oblong brain and brain bridge. Controls the frequency and depth of breathing.

2. Hemoreceptors: Located in the brain and large blood vessels. They respond to changes in the concentration of oxygen, carbon dioxide and pH of blood. An increase in the concentration of carbon dioxide or a decrease in pH of blood stimulate the respiratory center, increasing the frequency and depth of breathing.

3. Mechanoreceptors: Located in the lungs and respiratory tract. React to stretching the lungs and irritation of the respiratory tract.

II. Risk factors for lung diseases:

A. Smoking: The main risk factor for the development of chronic obstructive lung disease (COPD), lung cancer and other respiratory diseases. Tobacco smoke contains thousands of harmful chemicals that damage the respiratory tract and alveoli. Smoking also suppresses the immune system, increasing the risk of infections.

1. Chronic obstructive lung disease (COPD): A progressive disease characterized by a restriction of the air flow in the lungs. The main components of COPD are chronic bronchitis and emphysema. Chronic bronchitis is an inflammation of the bronchi, accompanied by increased mucus and cough products. Emphysema is the destruction of alveoli, which reduces the surface area for gas exchange. Smoking is the cause of about 80-90% of cases of COPD.

2. Lung cancer: The leading cause of death from cancer around the world. Smoking causes about 80-90% of lung cancer cases. The risk of lung cancer increases with an increase in the number of cigarettes smoked and smoking duration.

3. Other respiratory diseases: Smoking also increases the risk of asthma, pneumonia, bronchiolite and other respiratory diseases.

B. Air pollution: The effect of pollutants in the air (for example, solid particles, ozone, nitrogen dioxide) can damage the respiratory tract and alveoli, increasing the risk of respiratory diseases. Air pollution is especially dangerous for children, elderly people and people with existing respiratory diseases.

1. Solid particles (PM): Small particles that can penetrate deep into the lungs and cause inflammation and damage to tissues. Sources of solid particles include the burning of fossil fuel, industry, transport and natural phenomena (for example, dusty storms).

2. Ozon (O3): Gas formed as a result of the reaction of sunlight with nitrogen oxides and volatile organic compounds. High ozone concentrations can irritate the respiratory tract and cause difficulty breathing.

3. Nitrogen dioxide (No2): Gas formed as a result of the burning of fossil fuel, especially in automobile engines. It can irritate the respiratory tract and increase the risk of respiratory infections.

C. Professional harmfulness: The effect of some substances in the workplace (for example, asbestos, silica, coal) can lead to the development of occupational lung diseases, such as asbestosis, silicosis and pneumoconiosis.

1. Asstregaster: Lung disease caused by inhalation of asbestos fibers. Asbest is a mineral that was previously widely used in construction and industry. Asbestos fibers can cause scarring of lung tissue, which leads to difficulty breathing. Asbestos is also a well -known carcinogen and can cause lung cancer and mesotheliom (pleural cancer).

2. Silicosis: Lung disease caused by inhalation of silica dust. Freemage is contained in the sand, granite and other minerals. Silicosis is often found among mining workers, builders and stones.

3. Pneumoconiosis: The general term for a group of lung diseases caused by inhalation of mineral dust. Other types of pneumoconiosis include berylliosis (caused by inhalation of beryllium), siderosis (caused by inhalation of iron) and baridosis (caused by inhalation of barium).

D. Infections: Respiratory infections, such as pneumonia and influenza, can damage the lungs and increase the risk of developing chronic respiratory diseases.

1. Pneumonia: Lung infection caused by bacteria, viruses or fungi. Pneumonia can cause inflammation of the alveoli and filling them with liquid, which leads to difficulty breathing.

2. Flu: A viral infection that can affect the respiratory tract. Influenza can cause cough, fever, sore throat and general weakness.

3. Tuberculosis: Infectious disease caused by the Mycobacterium Tuberculosis bacterium. Tuberculosis usually affects the lungs, but can affect other organs.

E. Genetic factors: Some genetic factors can increase the risk of respiratory diseases such as asthma and cystic fibrosis.

1. Asthma: Chronic inflammatory disease of the respiratory tract, which is characterized by a reversible limitation of the air flow. Astma can be caused by allergens, irritants, physical activity and other factors. Genetic factors play an important role in the development of asthma.

2. MukoviScidoz: A genetic disease that affects the lungs, pancreas and other organs. Cycassocidosis causes the formation of thick mucus, which can clog the respiratory tract and lead to respiratory infections.

F. Age: With age, the function of the lungs decreases, which makes the elderly more susceptible to respiratory diseases.

G. Immunodeficiency states: People with a weakened immune system (for example, HIV/AIDS, patients receiving chemotherapy) have an increased risk of respiratory infections.

H. Passive smoking: Inhaling tobacco smoke exhausted by smokers, also increases the risk of respiratory diseases, especially in children.

III. Methods of prevention of lung diseases:

A. Refusal of smoking: The most effective way to prevent the development of many respiratory diseases. There are various methods that help quit smoking, including nicotin replacement therapy, drug treatment and consultations.

1. Nicotin -replacement therapy (NZT): Includes the use of nicotine plasters, chewing gum, candies, inhalers and nasal sprays. NZT helps reduce the symptoms of nicotine cancellation, such as craving for smoking, irritability and anxiety.

2. Medication: Some drugs (for example, Bupropion and Vareniklin) can help reduce smoking craving and increase the chances of successful smoking.

3. Consultations: Individual or group consultations with a doctor or psychologist can help develop strategies for overcoming craving for smoking and changes in behavior associated with smoking.

B. Avoiding air pollution:
