The primitive digestive cavity of an early embryo, formed during a stage called gastrulation when the embryo begins to develop its basic body structure.
From Greek 'archi-' (primitive) and 'enteron' (intestine), literally meaning 'first intestine,' this embryological term names the earliest digestive structure.
The archenteron is like nature's original blueprint—it appears in virtually all animals from sea urchins to humans, reminding us that we all share the same basic developmental recipe from our evolutionary past.
