Early Human Embryo Heart Development

This is a ventral view of early human embryos between 20 to 22 days (GA week 5 to 6).

These bright-filed microscopy images show the early heart tubes fusing in the midline to form a single ventral primordial heart tube. This fusion event begins cranially and extends caudally.
