Description
Summary:According to literature sources, the problem of morphological organization of trematodes' intestine has not been definitely solved [9]. According to the opinion of Fujino, Ishii, the shape of trematodes' intestinal microvilli does not depend on the host and on the helminth localization; at the same time, he suggested that this might be related to the systematic position of the parasite, in particular, with the taxa of higher rank than species or genus [13]. Analysis of X-ray diffraction patterns of the intestinal walls of trematodes indicates that the basal plate of the intestine is not developed. [...]filling the intestines and nutrients' movement in the intestinal cavity are mainly associated with the movement of microvilli of gastrodermis, and active process of "pumping" food performed by developed muscles of trematode's pharynx. According to Rees, Williams, Reynolds, well-developed basal plates provide mechanical stability to the structures where they are present, and thus, in different degrees may be obstacles to changing the shape of the organs and their relative size [23; 24].
