Structural and functional basis of absorption in an intestinal villus
Abstract
Predicting possible disturbances of functional parameters of tissue under strain is one of the major goals of functional anatomy. It is of particular interest for comprehension of vital functions’ development like absorption of nutrients in the intestine. In spite of multitudinous publications describing results of morphological studies of intestinal villus, these data are mostly fragmentary and lack complex approach. The present pioneer work is devoted to histophysiology of absorption in the intestinal villus as a model of interaction of blood microvessels with lymphatic ones, all of them intimately associated with transepitelial and interstitial metabolism. Lymphatic capillaries of the intestinal villus have been demonstrated during postnatal ontogenesis to stop olaying the part of main drainage system exchanging it for forming the oncotic pressure gradient which determines hemato-interstitial-lymphatic transport of intestinal villus in adult animals. Thus, studying structural and functional basis of intestinal absorption in the aforementioned aspect is of general biological and fundamental interest.
