Introduction

Stage22-CVS-icon.jpg
Cardiovascular
The individual serial slices have also been incorporated into a 3D model of this embryo.

The respiratory system is endodermal in origin, initially "budding off" the foregut during week 3. This bud forms the respiratory diverticulum, at the level of the glottis between the adult oesophagus and trachea. It continues to bud in week 4, forming a pair of lung buds.
