I have only found out very less on the oesophagus and I am still confused with the information I find from the resources in regards to fetal and embryo development differentiation. Below is what I have so far.

The primordium of the oesophagus is a portion between the respiratory diverticulum and stomach dilation. The oesophagus is a short tube initially but elongates significantly over time as the fetus grows. Oesophagus has an endoderm derived epithelial lining which proliferates. The epithelial lining also undergoes a series of transformations. Occluded lumen appears by week eight as well as vacuoles. With time the lumen is recanalized and the vacuoles combine. The epithelium of the oesophagus becomes stratified squamous during the fourth month. The development of muscle layers consisting of outer and inner layers, are recognised by eight weeks. The oesophagus contains smooth (splanchnic mesoderm derivative) and skeletal muscle fibres. --Z3414515 (talk) 12:20, 2 September 2014 (EST)

Caecum The caecum is located at the right bottom corner at the beginning of the fetal period. Towards the end of the fetal life it descends towards the right iliac fossa. This transition is heavily related to the ascending colon during this time.It is in the shape of a long tube during this fetal time and similar tot hat of a succule, the right side is larger.

Appendix The vermiform appendix increases markedly in length during the fetal period and is closely related to the growth of the caecum, so that at birth it becomes a worm-shaped tube arising from the distal end of the caecum.
