ТHE FORMATION OF STRUCTURES IN ONTOGENESIS, PROVIDING RESISTANCE TO METAPLASIA OF THE MUCOUS MEMBRANE OF THE LOWER THIRD OF HUMAN ESOPHAGUS

Studied features of vascular-tissue ratios of mucous membrane of the lower third of the esophagus of human fetus and adult persons as the basis of resistance of mucous membrane to metaplasia. It is shown that the formation of the inner layer of the lower third of the esophagus are in direct connection with the formation of how the structure of the body, so his vascularization.
