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).
However, as they only have a single stomach compartment, fermentation and digestion of cellulose primarily occurs in the large intestine and cecum. Digestive tract anatomy of hindgut fermenters. The stomach and small intestine of hindgut fermenters are similar in form and function to other non-ruminant herbivores.Food passes down the oesophagus and into the stomach (which does much the same job as the ruminant abomasums).igestive tract anatomy of hindgut fermenters.
