Powerful hydrochloric acid in the stomach helps break down the bolus into a liquid called chyme. A thick mucus layer that lines the stomach walls prevents the stomach from digesting itself. When mucus is limited, an ulcer (erosion of tissue) may form. Food is digested in the stomach for several hours. During this time, a stomach enzyme called pepsin breaks down most of the protein in the food. Next, the chyme is slowly transported from the pylorus (end portion of the stomach) through a sphincter and into the small intestine where further digestion and nutrient absorption occurs.
The sable (Martes zibellina) is a marten species, a small carnivorous mammal inhabiting forest environments, primarily in Russia from the Ural Mountains throughout Siberia, northern Mongolia. Its habitat also leans the borders of eastern Kazakhstan, China, North Korea and HokkaidÅ in Japan.
In Russia, the sable's distribution is largely the result of mass reintroductions involving 19,000 animals from 1940 to 1965. Their range extends northward to the limit of trees, and extends southward to 55â60Â° latitude in western Siberia, and 42Â° in the mountainous areas of eastern Asia.able furs were coveted by the nobility of the Russian Empire, with very few skins ever being found outside the country during that period. Some however would be privately obtained by Jewish traders and brought annually to the Leipzig fair. Sometimes, sable hunting was a job given to convicts exiled to Siberia.
