    Uploaded by

    Ebraheem Negm
    The document summarizes respiratory system development and congenital anomalies of the trachea, bronchi, and lungs. It discusses: 1. The formation of the respiratory diverticulum in the fourth week is the first sign of respiratory system development. 2. The tracheal epithelium and glands are derived from endoderm while the tracheal smooth muscle, connective tissue, and cartilage rings are derived from mesoderm. 3. Congenital anomalies of the trachea include tracheoesophageal fistula and those associated with esophageal atresia.
