A set of 35-week gestation twins are found to have neonatal respiratory distress syndrome. What cell within pulmonary tissue has not reached maximal function, leading to this diagnosis?
Understand the Problem
The question is asking about the specific type of cell in pulmonary tissue that is not fully developed in a set of premature twins who have neonatal respiratory distress syndrome. This involves understanding respiratory physiology and the role of specific cell types in lung development.
Answer
Type 2 pneumocytes.
The final answer is Type 2 pneumocytes.
Answer for screen readers
The final answer is Type 2 pneumocytes.
More Information
Neonatal respiratory distress syndrome is primarily due to inadequate surfactant production by Type 2 pneumocytes. Surfactant deficiency leads to increased surface tension and alveolar collapse, characteristic of RDS.
Tips
A common mistake is confusing Type 1 and Type 2 pneumocytes. Type 2 pneumocytes synthesize and secrete surfactant, essential for lung function.
