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 scientific name for lung cells?

Pneumocyte. There are two types: Type I cells make up the lining of the air sacks (alveoli) in the lung, type II cells produce a slick liquid called surfactant that helps coat the alveoli and keep them from collapsing when we exhale.


What describes the role of surfactant in the respiratory system?

Surfactant helps reduce surface tension within the alveoli, thus preventing each alveolus from callapsing as air moves in and out during respiration.


What substance helps maintain inflation of the alveoli so that they do not collapse on themselves during inspiration?

A product of the lung tissues called surfactant keeps the tiny alveoli open.


What type of cartilage is bronchi?

No, bronchioles (except in the whale) do not contain cartilage. The bronchioles in whales contain cartilage in order to prevent them from collapsing before other parts of the airways (and trapping gas in the alveoli). This helps prevent the bends - as nitrogen is removed from the alveoli before large pressures cause it to diffuse across the thin walls present there.


What do the cartilage rings in the trachea allow to happen?

it helps to prevent trachea from collapsing by maintaining definite shape


Alveoli have neither smooth muscle or mucous secreting cells?

That is correct. Alveoli only contain only two types of cells: Type I cells that are like thin sheets and make up the actually wall of the alveoli, and Type II cells that secrete a substance called surfactant that helps to hold the alveoli open. There can also be some macrophages present in the alveoli to destroy invading bacteria.


Why is 5 months premature baby safer than 6 months premature baby?

This is not true as surfactant, which helps to keep the lungs open and prevents the alveoli from sticking together, is not formed until 37 weeks gestation.


Does surfactant means to keep alveoli open and helps premature babies survive?

Quite often, surfactant is not fully present in premature babies which is why they tend to need extra breathing support when they are born.If doctors are able to hold off on the imminent birth of a premature baby, they will give the mother injections of steroids to try & speed up lung development.Surfactant reduces the surface tension of the lungs and allows them to expand, which is important for breathing.


How the system helps the body?

It prevents you from collapsing like a blob of jello.


Alveoli are part of what organ?

lungs and helps in gaseous exchange.


What does the alveoli do in humans?

it helps ur lungs breath better a exchanges gases
