The digestive system of the Ophryoscolescides includes different parts : the adoral ciliary zone, the cytostome, the oesophagus, the endoplasm, the rectum and the anus. The endoplasm appears as a digestive sack surrounded by the mesoplasm. This fibrillary envelop separates it from the ectoplasm. It's in the endoplasm that the mechanism of the digestion develops. The endoplasm contains many different structures. It includes macrovesicles of three types, bacteria, plant-particles, microvesicles of two types, ergastoplasm, polysaccharides, the Golgi apparatus and fibrils. The macrovesicles of the first and the second type are not to be found simultaneously in the same endoplasm. The macrovesicles of the third type, very few in number, are different of the previous ones by their double membrane and their denser granulations. Large-sized vesicles contain bacteria at different stadia of digestion. At the end of the digestion, the bacteria are completely or partially degraded. The plant-particles ingested by the Ciliate are to be found in the endoplasm, surrounded by a vesicle. A first type of microvesicles are found in the oesophagus and in the rectum. They are distinguished by a deep black coloration of variable shape. Another type of microvesicles is also present in the endoplasm. They are small bright vesicles that can bud from large-sized vesicles. In the endoplasm the ergastoplasmic lamellae and rings are easily recognizable thanks to the ribosomes, that edge their external membrane. The ribosomes are also situated along the mesoplasm, around polysaccharidic grains and in small groups between the other endoplasmic elements. The polysaccharidic grains are netting-needle shaped bodies. Noirot-Timothee confers them a reserve function. The Golgi apparatus includes eight to eleven saccules. The extremities of those saccules present swellings or golgian ampullae. The endoplasm is also strewn with fibrillary structures that, cross-section are arranged in groups of four or five tubules. This type of endoplasm is found in Ophryoscolescides taken from a ruminant that has been fasting for several hours. In some individuals the endoplasm can have a totally different aspect. It is filled with vesicles of quite different sizes and shapes. The localization test of the acid phosphatase reveals, in this type of endoplasm, lead deposits. These vesicles are probably autophagic vesicles.
口纤毛区、胞口、食管、内质、直肠和肛门。内质表现为一个被中质包围的消化囊。这种纤维状包膜将其与外质分隔开来。消化机制正是在内质中发展的。内质包含许多不同的结构。它包括三种类型的大泡、细菌、植物颗粒、两种类型的小泡、内质网、多糖、高尔基体和纤维。第一类和第二类大泡不会同时出现在同一内质中。第三类大泡数量极少，其双层膜和更致密的颗粒与前两类不同。大型泡在不同消化阶段含有细菌。消化结束时，细菌会被完全或部分降解。纤毛虫摄取的植物颗粒存在于内质中，被一个泡包围着。第一类小泡存在于食管和直肠中。它们的特点是形状各异，颜色深黑。另一类小泡也存在于内质中。它们是小而明亮的泡，可以从大型泡上出芽。在内质中，由于核糖体附着在外膜边缘，内质网的片层和环很容易辨认。核糖体也沿着中质分布，围绕着多糖颗粒，并在其他内质成分之间成小群分布。多糖颗粒是网针状的物体。诺罗 - 蒂莫西赋予它们储存功能。高尔基体包括八到十一个扁平囊。这些扁平囊的末端有肿胀或高尔基体壶腹。内质中还散布着纤维状结构，其横截面由四或五个小管组成一组。这种类型的内质存在于取自禁食数小时的反刍动物的奥弗里斯科列斯虫中。在一些个体中，内质可能呈现出完全不同的样子。它充满了大小和形状截然不同的泡。酸性磷酸酶的定位测试显示，在这种类型的内质中有铅沉积物。这些泡可能是自噬泡。
