What does a surfactant do?
The main function or job of a surfactant is to reduce surface tension. This process is used on liquids while it dissolves.
What is the function of type 2 alveoli walls?
function of type 2 alveoli cells is to secrete surfactant.
What would in surfactant absence?
In the event of surfactant absence in the lungs they would collapse and pulminary functioning would be reduced dramatically. Surfactants are critical in maintaining proper lung function by reducing surface tension and making it easier to breathe.
What do surfactant do?
A surface-active agent 'surfactant' usually cleans something. ie -soap is a surfactant.
Surfactant that cover the respiratory membranes?
Surfactant is pleural fluid.
What is the interfacial properties of surfactant solution?
What is the interfacial properties of surfactant solution?
What do Type 2 alveolar cells secrete?
secrete surfactant
How effective is surfactant therapy?
Normally surfactant replacement therapy keeps the infant alive until the lungs start producing their own surfactant.
How do the structures of the alveoli and capillaries support the function of gas exchange?
Alveoli are found within the lungs. The alveoli act as a specialised gaseous exchange surface in mammals. Another function of alveoli is the production of surfactant.
Which surfactant lacks in a new born baby?
I have never heard the surfactant called anything specific. Full term babies usually have surfactant (a mixture of lipids (fats) and proteins). Premature babies many times do not have enough surfactant to keep the alveoli of their lungs open, so artificial surfactant is put into the trachea, sometimes more than once.
Why does oil miscible in solution of surf and water?
Presumably you mean surfactant and water? A classic surfactant molecule has a polar, hydrophilic end and a non-polar hydrocarbon liophilic end. With enough of a suitable surfactant, oil droplets will form with the liophilic part of surfactant molecules dissolved in the droplets and water molecules attached to the hydrophilic part of the surfactant. The oil disperses in the water.
When do fetuses begin to produce surfactant?
Fetuses begin to produce surfactant between weeks 24 and 28.
