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.
Am pretty sure its called the pulmonary surfactant that's produced from the lungs
type II alveolar cells
penis
what is the name of the liquid layer that lines the alveoli
A surface-active agent 'surfactant' usually cleans something. ie -soap is a surfactant.
True; produced by Type II pneumocytes
In the young fetus, they are produced in the liver. By late pregnancy, they are produced in the bone marrow.
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.
The carbon dioxide produced by a developing fetus is removed by the mother's placenta. The placenta facilitates the exchange of gases between the mother and the fetus, allowing the carbon dioxide to be carried away in the mother's bloodstream and eliminated through her own respiratory system.
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.
no when Rh negative blood from the fetus interacts with Rh+ blood of the mother there will be no antibodies produced due to absence of antigen on the Rh- blood cells and when Rh positive is mixed with Rh negative blood of fetus no response is produced due to the fact that the fetus has an underdeveloped immune system
