The developing fetus does not produce lung surfactant until late its development.Explain what problem a premature infant would have if it were born before it had produced surfactant?
The lung surfactant is a substance that coats the internal surfaces of the alveoli (air sacks) of the lungs and prevents them from sticking together in the deflated state when the baby exhales. If the infant is born before it produces lung surfactant, then the alveoli will be unable to be filled with air and the baby will suffocate.
Name of surfactant that breaks surface tension in the lungs?
Am pretty sure its called the pulmonary surfactant that's produced from the lungs
Lung surfactant is produced by?
type II alveolar cells
Where is fetus produced?
penis
What is the fluid that lines the alveoli is produced by?
what is the name of the liquid layer that lines the alveoli
What would in surfactant absence?
In the absence of surfactants, the surface tension of the liquid would be higher. This can lead to poor wetting and spreading of the liquid on a surface, impacting processes like cleaning, emulsification, and foaming. Surfactants help lower the surface tension, allowing them to perform these functions effectively.
What do surfactant do?
A surface-active agent 'surfactant' usually cleans something. ie -soap is a surfactant.
True or false the fluid coating the alveoli that reduces surface tension is called surfactant?
True; produced by Type II pneumocytes
The chemical on the inside of the alveoli that allows it to keep its round shape is?
Surfactant is the chemical on the inside of the alveoli that helps it maintain its round shape by reducing surface tension, preventing collapse. This substance is produced by type II alveolar cells in the lungs.
What produces surfactant?
Surfactant is produced by the type II alveolar cells in the lungs. These cells secrete surfactant which helps lower surface tension in the alveoli, preventing collapse and facilitating gas exchange.
Where does the formation of blood cells take place?
In the young fetus, they are produced in the liver. By late pregnancy, they are produced in the bone marrow.
Reduces the surface tension of the fluid in the alveoli?
Surfactant, a substance produced by type II alveolar cells in the lungs, reduces the surface tension of fluid in the alveoli. This helps to prevent the collapse of alveoli during expiration and facilitates the exchange of gases in the lungs.
