[Temporal organization of the functioning of enterocyte cytoplasmic structures during the process of absorption].
The dynamic on fat and protein absorbtion was followed in epithelial cells of the small intestinal villi in mature and newborn rats. General and specific mechanisms participating in processes of marginal enterocyte absorbtion, duration of separate phases, participation of cytoplasmic structures in transporting the absorbed substances were stated. Temporal parameters in functioning enterocytic membrane structures were revealed. Coordinative activities of enterocytic organelles, structural-functional units of the organ, processes on absorbtion and secretion demonstrate close functional and anatomical interconnections existing between separate structures. Absorbtion, as one of the most essential biological processes, has an inherent property of alternate activity of the functioning structures, their continuity and intermittence depending on the level studied.
