Stage14 Respiratory Tract Development

This diagram is designed to show the association between the foregut and the early respiratory system at about stage 13 to 14 (week 4-5) of development.

Excerpts of the histology sections and their approximate level are shown in the cartoon of the embryonic respiratory/gastrointestinal tracts.

  • initial bifurcation of foregut (oesophagus) and respiratory (trachea).
  • heart (ventral) and the dorsal aortas (dorsal) to the lung buds.
  • stomach below the lung buds.
  • narrow pleural canals outside the lung buds.
