Lung Surfactant

Lung surfactants, also known as antiatelexic factor, are one of the most important mechanisms for regulating breathing and removing harmful substances from the bloodstream.

The surface active substance consists of proteins, fats and carbohydrates, which promotes the absorption of oxygen in the pulmonary capillaries and the release of carbon dioxide into the alveoli. This allows the respiratory tract to function more efficiently and prevents various respiratory diseases.

However, not all lung surfactants are created equal. Some of them provide increased lung function and improved exchange of oxygen and carbon dioxide, while others help activate various enzymes and increase the anti-allergic activity of the immune system.

It should be noted that the surface active substances of the lungs can change under the influence of various factors, such as physical activity, nutrition, pharmacological drugs and stressful situations. Also, in long-term diseases affecting the lungs or respiratory system, the production of surfactants

Lung surface active substances

Lung surface active substances are molecules that can change the surface tension of the blood. They promote the redistribution of water between blood and tissue, which is an important condition for the normal functioning of the respiratory system. Research shows that surface active substances are one of the main factors influencing the development of atelectotic changes in lung tissue and the brain.

In medicine, surface active molecules of the lungs are widely used for the diagnosis and treatment of diseases of the respiratory system. Among them:

Pulmonary function monitoring. Blood surface tension is used to assess the ability of the alveoli to release oxygen into the bloodstream and remove carbon dioxide from the blood. Normally, the lungs must maintain a certain level of surface tension, which can change under the influence of many factors.

Determination of the level of functional pulmonary disorders. Changes in blood surface tension are used to diagnose functional lung disorders such as pulmonary distress syndrome or emphysema. This allows doctors to more accurately assess the patient’s condition and take appropriate measures to treat and prevent diseases.

Assessing the body's response to medications. The surface active component of the blood can affect the metabolism of certain drugs. Therefore, assessing its level can help the doctor understand which medications may cause allergic or toxic reactions.
