Lungs and frequency therapy

**Encyclopaedia entry: Lungs** **Definition:** The lungs are a vital organ of the respiratory system responsible for the exchange of gases between the air and the blood. It enables the intake of oxygen and the release of carbon dioxide, a waste product of metabolism. **Anatomy:** - **Lungs:** Humans have two lungs - the right lung, which consists of three lobes, and the left lung, which consists of two lobes to make room for the heart. - **Bronchi:** The trachea divides into two main bronchi that lead into the lungs and branch out into smaller bronchioles. - **Alveoli:** Tiny air sacs at the end of the bronchioles where gas exchange takes place. The alveoli are surrounded by a network of capillaries. **Functions:** - **Gas exchange:** Oxygen from inhaled air diffuses through the walls of the alveoli into the blood, while carbon dioxide from the blood enters the alveoli to be exhaled. - **pH regulation:** The lungs help regulate the body's acid-base balance by influencing the level of carbon dioxide in the blood. - **Particle filtration:** The airways filter dust, pollen and other particles from inhaled air. - **Immune defence:** The lungs contain immune cells that fight pathogens. **Diseases:** - **Asthma:** A chronic inflammation of the airways that leads to shortness of breath and wheezing. - **Chronic obstructive pulmonary disease (COPD):** A progressive disease characterised by shortness of breath and coughing. - **Pneumonia:** An infection of the pulmonary alveoli caused by bacteria, viruses or fungi. - **Lung cancer:** A malignant neoplasm often associated with smoking. - **Lung fibrosis:** A disease in which the lung tissue becomes scarred and hardened, making breathing difficult. **Diagnosis:** - **Lung function tests:** Measure the volume and speed of air inhaled and exhaled. - **Imaging procedures:** X-ray, CT or MRI to assess the structure of the lungs. - **Blood gas analysis:** Determines the oxygen and carbon dioxide content in the blood. **Prevention and care:** - Avoid smoking and passive smoking. - Regular physical activity to support lung function. - Vaccinations against influenza and pneumococci to prevent infections. - Avoid air pollution and harmful substances in the air Avoiding air pollution and harmful chemicals. **Fun facts:** - The lungs have a large surface area, about the size of a tennis court, to allow efficient gas exchange. - The breathing rhythm is unconsciously controlled by the respiratory centre in the brain, but can also be influenced voluntarily. **Research:** Research on the lungs focuses on developing new treatments for lung disease, improving diagnostic procedures and understanding the effects of environmental factors on lung function.
