Am pretty sure its called the pulmonary surfactant that's produced from the lungs
Surfactant! or 'Pulmonary Surfactant' Just had one of those moments too :)
The lipid-based molecule that coats the air-exposed surface of the alveolus is called pulmonary surfactant. Pulmonary surfactant reduces surface tension, preventing alveolar collapse and allowing for efficient gas exchange in the lungs.
The cost of surfactant can vary depending on the type, quantity, and brand. Generally, prices range from $10 to $50 per gallon. It is recommended to check with suppliers or retailers for specific pricing information.
surface tension of fluid lining the alveoli pull fluid from alveolar wall by average pressure= -3 mmHg in normal lung , but without surfactant it's increased to -20 mmHg , thus massive filtration of the fluid leads to pulmonary edema .
The Great (Type 2) Alveolar cells secrete pulmonary surfactant and prevent the cells from collasping.
Pulmonary surfactant...see link for more information.
A surfactant is a substance that, when mixed with a liquid, reduces its surface tension. There are usually two or more surfactants in a bar of soap.
Alveoli does not collapse because lungs always have a residual volume which prevents the alveoli to collapse.
A surface-active agent 'surfactant' usually cleans something. ie -soap is a surfactant.
The fluid in the alveoli of the lungs is called pulmonary surfactant. It helps to reduce surface tension and prevent the alveoli from collapsing, allowing for efficient gas exchange during respiration.
Type II alveolar cells in the lungs secrete surfactant, which is a specialized fluid that lowers surface tension in the alveoli. This reduces the tendency for the alveoli to collapse during exhalation and helps maintain the elasticity of the lungs for efficient gas exchange.
