The intestinal phase of secretion begins at transition of a chemical moustache from a stomach in intestines. The chemical moustache influences on hemo - osmo - механорецепторы intestines and is reflex changes intensity of gastric secretion. Depending on degree of hydrolysis of food substances, in a stomach the signals raising gastric secretion or, on the contrary, the braking arrive. Stimulation is carried out at the expense of local and central reflexes and realised through a wandering nerve, внутриорганную nervous system and гуморальные factors (allocation гастрина by G-cages of a duodenal gut). This phase is characterised by the long latent period, the big duration. Acidity of gastric juice during this period the low. Braking of gastric secretion occurs at the expense of allocation секретина, ХЦКПЗ which oppress secretion of hydrochloric acid, but strengthen secretion пепсиногенов. Reduce production of hydrochloric acid also глюкагон, ЖИП, ВИП, нейротензин, соматостатин, серотонин, бульбогастрон, products of hydrolysis of fat. It is the higher form of reflexion of the validity. By means of consciousness forms of contact of the person with world around are purposefully regulated. The consciousness represents the subjective experiences of the validity proceeding against experience existing at the individual and сознаваемые by it as certain subjective reality. Correlation of the saved up knowledge with reality and their inclusion in individual experience - is process of comprehension of the validity. In urine urea, uric acid, ammonia, пуриновые the bases, креатинин contain; in a small amount - derivatives of products of rotting of fibers in intestines (индол, скатол, phenol).
