The primitive gut that forms during gastrulation in the developing embryo is known as the archenteron or the digestive tube.It develops into the digestive tract of an animal.ach is controlled by the dorsal blastopore, and primitive node (also known as Hensen's node), respectively. During Gastrulation, the Archenteron develops into the digestive tube, with the blastopore developing into either the mouth (Protostome) or the anus (Deuterostome).
The alimentary canal (gut) is a muscular tube that runs from your mouth to your anus. A bolus of food moves through the gut by waves of muscular contractions (peristalsis) that occur throughout the length of the gut; this is lubricated by mucus which helps move the food along.This so food can be ultimately converted into energy to be used by the body.he alimentary canal (gut) is a muscular tube that runs from your mouth to your anus.
