Bile - a secret polygon liver cells. Bile contains bile acids (see), bile pigments (see), cholesterol (see). Bile secretion occurs constantly. During the day, the liver of an adult highlights from 500 to 1200 ml of bile. There are liver and gallbladder bile, which are very different in color and consistency. The value of bile in the digestion and absorption of nutrients due mainly to the presence of bile acids, enhancing peristalsis of the bowel, and the degree of emulsification of fats in the intestinal juice and speed of their decomposition. The secretion of bile in the intestine are regulated as certain hormones (for example, secretin)and a number of dietary factors (fats milk and eggs). Salts of magnesium enhances the secretion of bile. As cholagogue also used bile acids. Reducing secreting or bile outflow, for example due to the formation of stones (see Gallstone disease), causes the metabolism disorders, in particular to the disorders of fat metabolism.
Bile is used in nutrient media for cultivation of microbes (bruchkomitsky, tuberculosis).
