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).
Iâve written at length how microflora in the gut benefits our overall health. The ways in which this occurs make for an impressive listâso much so that itâs possible to lose track of these microorganismsâ more immediate effects, which occur in the digestive tract itself. Here are a few of the most important ways healthy gut bacteria help keep the digestive system working smoothly: 1  Help digest and absorb foods. 2  Acidify the colon and normalize bowel movements. 3  Eliminate gas problems and sweeten breath. 4  Support the ability to digest dairy products.
