Ileum is the lower part of the small intestine and the largest section of the alimentary canal. The inner walls of the ileum contain secretory cells, some of which secrete mucus and others secrete an alkaline fluid known as internal juice or succus enetericus. The arrival of chyme in the ileum stimulates the secretion of intestinal juice. The juice contains four enzymes that carry out digestive functions as follows:- maltase; speeds up the breakdown of maltose to glucose, sucrase; speeds up the breakdown of sucrose into glucose and fructose, peptidase; beaks down peptides into amino acids,lipase; breaks down lipids into fatty acids and glycerols. The process of digestion is therefore completed in the ileum. The resulting watery emulsion of food is called chyle and contains soluble products of digestion ready to be absorbed. The entire canal is lined with epithelial membrane that contains goblet cells which secrete mucus. The mucus allows smooth movement of food materials and also coats the wall of the alimentary canal thus protecting it from being digested by the enzymes.
