Embryology and Development of the Respiratory System

The respiratory system develops from the primitive foregut during embryogenesis. Initially, a respiratory diverticulum forms, which will eventually give rise to the trachea, bronchi, and lungs. The respiratory system primarily develops through branching morphogenesis, a process where the structures divide and expand. Epithelial-mesenchymal interactions during development play a crucial role in the differentiation and maturation of respiratory tissues. At around week 4 of development, the trachea...
