Type II Alveolar Cells | Pulmonary Surfactant

The video tutorial explains the differences between Type 1 and Type 2 alveolar cells, focusing on the role of Type 2 cells in producing pulmonary surfactant. This surfactant is crucial in reducing surface tension within the alveoli, preventing their collapse and ensuring efficient gas exchange. The tutorial also discusses the challenges faced by premature infants who lack the ability to produce surfactant, leading to potential respiratory issues. Solutions such as ventilators and surfactant injections are highlighted as interventions for these infants.

Explain the role of water molecules in the alveolus and their interaction with surfactant.
