Bile juice is yellowish-green or greenish-blue alkaline (pH-7.7) fluid. It contains about 90% water, 60% bile salts, 3% bile pigments etc. The common bile salts are sodium chloride, sodium bicarbonate, sodium glycocholate and sodium taurocholate. Cholecytokmin directely stimulate contraction of gall bladder and bile flow starts. Secretin regulate the secretion of pancreatic juice, like that of gastric juice. Secretin is a single chain polypeptide of low molecular weight with 27 amino acids residue. - The entery of lipids into the duodenum opperently causes the liberation of enterogastrone by the intestinal wall which inhibits the gastric juice secretion. Enterocrinin is secreted by intestinal lining into blood stream and control the secretion of intestinal juice.
