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 is the function of the surface of fluid lining the alveolar?

The fluid lining the inner alveolar membrane is called surfactant. It helps reduce the surface tension in the alveoli, which prevents them from collapsing in on themselves every time we exhale.


What is the fluid in the alveoli called?

Pneumonia.


How can you explain surface tension?

it's attraction force that attract the surface of fluid toward under


What is the difference between viscosity and surface tension?

Viscosity is the resistance of flow and surface tension is the lateral force of the bonds between the molecules. Of course, viscosity is resistance of flow and surface tension of lateral force but viscosity is s display of frictional force during laminar flow caused due to intermolecular forces. The surface tension is a function of cohesive forces generated by intermolecular forces among similar molecules. Very rightly since both the parameters are dynamic in natures and hence a 3rd parameter noted as friccohesity is most advanced version of the contribution of the intermolecular forces operational in liquid dynamic behavior. The friccohesity along with surface tension, viscosity, wetting coefficient, interfacial tension are measured with borosil mansingh survismeter.

Surfactant helps to prevent the alveoli from collapsing by what?

Interfering with the cohesiveness of water molecules, thereby reducing the surface tension of alveolar fluid.


How does surfactant affect the total air flow into lungs?

Surfactant is similar to a detergent, it keeps the fluid coating the lining of the alveoli from creating surface tension. This allows the alveoli to expand without hindrance, and allows greater air flow.


What is the role of surfactant in the lungs?

AnswerSurfactant reduces surface tension, so that the alveoli in the lungs are able to expand. It is essentially a biological detergent.Surfactant reduces surface tension. Without surfactant, the wet surfaces of the alveoli in your lungs would stick together and your lungs would not be able to expand - so, you would not be able to breath. The alveoli are the tiny sacs in your lungs where oxygen is captured from inhaled air and absorbed into your bloodstream. They are very small and are have moist surfaces. Wet surfaces stick together due to surface tension, which is caused by the attraction that water has for itself. To demonstrate how strong surface tension is, take two small glass panes, wet them slightly and press them together until there is no air between them. Now try to pull them apart. It's extremely difficult (you usually have to slide them apart because they will not separate otherwise). However, if you mix dish detergent in the water first, it will be much easier to pull them apart, because the detergent is a surfactant - a substance which combines with water and by doing so reduces the surface tension of the water.About three to four weeks before birth, you lungs begin to produce surfactant. When you are born and take your first breath, you have to open the fluid-filled alveoli to allow air in. Without surfactant, this would be nearly impossible, which is which very premature infants have so much difficulty breathing. These very early preemies are given surfactant (either artificial or derived from calf lungs) down a tube going to their lungs, to help their alveoli open and allow air entry.Some medical conditions cause loss of surfactant. In pulmonary edema, fluid from the blood invades and floods the alveoli. Among other problems, this causes dilution and washout of the surfactant, so that alveoli are more likely to collapse. Inflammation of the lungs also causes reduced surfactant production, so again the alveoli collapse due to increased surfaced tension. In cystic fibrosis, excess mucus production displaces the surfactant (and mucus has an even higher surface tension than water). Patients with CF are given extra surfactant to make up for this loss and to provide enough surfactant that it can act on the mucus as well as the normal alveolar fluid.


How surfactant prevents from pulmonary edema?

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 .
