- Freebase(0.00 / 0 votes)Rate this definition: Surfactant. Surfactants are compounds that lower the surface tension of a liquid, the interfacial tension between two liquids, or that between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.

Alveolar Surface Tension and Surfactant in the Compliance of the Lungs Alveolar surface tension is important for the lungs to function efficiently. Surfactant is a lining in the alveoli made of lipids and proteins. Surface tension of the alveoli are important to keep the alveoli shape, but surfactant is needed to regulate surface tension.

- Without normal pulmonary surfactant present, the attractive forces of the water will cause the alveoli to collapse. Pulmonary surfactant is a complex substance in the lungs which reduces the surface tension of water and therefore, prevents the collapse of the alveoli.

Anionic Surfactant The anionic surfactants help in lowering the surface tension of the water or any other liquid as they act as active surface agents. An Anionic surfactant binds the impurities and dirt particles suspended in the fluid which makes it a useful and efficient cleansing agent.

surfactant 2 also called pulmonary surfactant. one of certain lipoproteins that reduce the surface tension of pulmonary fluids, allowing the exchange of gases in the alveoli of the lungs and contributing to the elasticity of pulmonary tissue. See also alveolus, atelectasis, surface tension.

Pulmonary surfactant Because during ventilation there is a variation of the lung surface area, the surfactant's interface concentration is not usually at the level of saturation. The surface increases during inspiration, which consequently opens space for new surfactant molecules to be recruited to the interface.

- Examples of adjuvants are surfactants, spreader stickers, crop oils, anti-foaming materials, buffering agents, and compatibility agents. Surfactants are adjuvants that facilitate and accentuate the emulsifying, dispersing, spreading, wetting, or other surface modifying properties of liquids.

Pulmonary surfactant Surfactant immune function is primarily attributed to two proteins: SP-A and SP-D. These proteins can bind to sugars on the surface of pathogens and thereby opsonize them for uptake by phagocytes. It also regulates inflammatory responses and interacts with the adaptive immune response.

- In the lung the major product secreted by exocytosis is surfactant, a complex, phospholipid-rich, lipoprotein-like material lining the respiratory surface. By lowering surface tension at the air–liquid interface, surfactant is an important determinant of lung compliance and prevents alveolar collapse. It may have the additional functions of preventing lung edema and assisting inflammatory responses (3, 4).

- Some homemade recipes include a soap which is a type of surfactant, but one that is very sensitive to the quality of water being used. If you have moderate to hard water, you can experience problems when using soap in your wash routine-such as a residue, which can cause your diapers to repel liquid instead of absorb it.

- Cationic surfactants are not widely used for pest control, but they are more commonly used in heavy-duty cleaning compounds. Don’t grab a bottle of engine wash surfactant used to clean the tractor and add it to your pesticides when spraying Easter lilies. The results can be devastating.

What is a Surfactant? Many companies manufacture a range of surfactants for various purposes, ranging from soaps to inks. They are also sometimes referred to as “ wetting agents .”. The term is a compound of “surface acting agent,” referring to the fact that these substances interact with the surface of a liquid to change its properties. They work through a process known as “adsorption,” which means that they accrete on the surface of a liquid, creating a film that reduces its surface tension.

surfactant Surfactant reduces the surface tension of fluid in the lungs and helps make the small air sacs in the lungs (alveoli) more stable.f the surface tension is lowered, the attraction among molecules of the fluid is decreased and the surface area of the fluid increases. For example, if a drop of detergent is added to a drop of water, the detergent reduces the surface tension and the drop of water flattens out.

- How surfactant. helps your baby's lungs. To learn how surfactant helps your baby, you will need to know what these words mean: Alveoli Alveoli are tiny air sacs in the lungs. Alveoli fill up or expand when air goes. into the lungs. When air leaves the lungs, the alveoli become smaller, but do. not collapse. In these tiny air sacs, the baby’s blood gets oxygen.

surfactant Surfactant prevents this collapse by reducing the surface tension of the fluids that line the lungs and helping to equalize the pressures between large and small air spaces. Surface tension is a measure of the attraction molecules of a fluid have for each other.or example, if a drop of detergent is added to a drop of water, the detergent reduces the surface tension and the drop of water flattens out. In the lungs, surfactant reduces the surface tension and helps to maximize the surface area available for gas exchange.
