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.

How do fat and protein film lining the inner wall of the aveoli do in your reapiratory system?
Pulmonary surfactant is a surface active material composed of lipids and proteins which is found in the fluid lining the alveoli.Surfactant prevents alveolar collapse. In addition, it is involved in the protection of the lungs from injuries and infections caused by inhaled particles and micro-organisms.
A specialized function shared by the many cells lining the lungs and the lumen of the gut is?
A specialized function shared by the many cells lining the lungs and the lumen of the gut is increased exchange surface provided by their membranes. Interstitial fluid provides for the exchange of materials between blood and body cells.
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 structure of alveolar ducts?
it dissolves oxygen in the fluid and from there it can diffuse to the alveolar cells.It goes right back to evolution where single cells have to absorb oxygen from water.All of our cells systems ae aquatic.
Reduces the surface tension of the fluid in the alveoli?
surfactant
What keeps the surface between the air and the alveolar cells moist in the lung?
alveolar fluid
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 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 .

In addition, it is involved in the protection of the lungs from injuries and infections caused by inhaled particles and micro-organisms.
How does the fat and protein film lining the inner wall of the alveoli protects the respiratory system?

Explain how the changes in alveolar structure cause a decrease in blood oxygen levels in emphysema?
Pneumonia fills the lung's alveoli with fluid, keeping oxygen from reaching the bloodstream.
Expiration depends on what two factors?
Expiration depends on (1) the recoil of elastic fibers stretched during inspiration and (2) the inward pull of surface tension from the film of alveolar fluid.
Which of the choices below describes the forces that act to pull the lungs away from the thorax wall and thus collapse the lungs?
the natural tendency for the lungs to recoil and the surface tension of the alveolar fluid
What is a subarticular cyst?
A subchondral cyst is a fluid-filled sac under the cartilage.
What secretes a fluid containing surfactant in the respiratory system?
type II alveolar cells
What is the function of ependymal cells?
responsible for the lining of ventricular cavities (of brain). Other than the above-mentioned function, they also line the central canal of spinal cord. It is involved in the production of cerebrospinal fluid (CSF).
