Surfactant improves airflow in several ways. First, it maintains airway stability by preventing airway film collapse of the airway walls. Second, surfactant modulates airway wall thickness and diameter by regulating liquid balance. In other words, the dysfunction of surfactant airways might be one of the mechanisms leading to increased airway resistance [seen in in obstructive lung diseases].

Is cyclodextrin a nonionic surfactant?
yes
What would happen if surfactant were not present?
Without surfactant, the wet surfaces of the alveoli in your lungs would stick together and your lungs would not be able to expand.

As a result of the tidal volume change what happens to the flow into each lung and total air flow?
Airflow increases when surfactant is applied because the resistance to lung inflation has been reduced.
How would an object blocking a bronchus affect this airflow?
you die
What do surfactant do?
A surface-active agent 'surfactant' usually cleans something. ie -soap is a surfactant.
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.
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
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.
How effective is surfactant therapy?
Normally surfactant replacement therapy keeps the infant alive until the lungs start producing their own surfactant.
What are the types of airflow?
types of airflow, functions of airflow, properties of airflow,
Does low coolant effect cool airflow from the AC?
No it does not affect air flow. The air will just not be as cool.
