IV. Bile and succus entericus are alkaline liquids. What effect would you expect them to have on the digestion of fat ? The liver. The liver is the largest gland in the body. It is situated on the right side of the body, and covers part of the stomach, small intestine, and large intestine. The upper surface fits closely into the under surface of the diaphragm. The liver secretes an alkaline juice, yellowish-green or brown in color, called bile. This pours, by means of the bile duct, into the small intestine only during the period of digestion. The alkali in the bile activates the digestion of fats and helps in the absorption of digested fats. The excess bile passes through another duct into the bile sac or gall bladder, where it is stored until needed. Sometimes a part of the bile substance crystallizes in this duct, forming gallstones. In such a case, the bile duct is closed and the excess bile passes into the blood, causing jaundice. Intestinal digestion. The presence of food in the small intes- tine stimulates the flow of intestinal juice which contains a num- ber of enzymes. An intestinal protease, erepsiuy helps to convert the proteoses and peptones formed in the stomach into the end products of digestion, amino-acids. Several inverting enzymes in the intestinal juice convert the double sugars into single or. small intestine; Not far below the stomach, a tube empties into the intestine. This tube leads from the pancreas, the liver, and the gall bladder, and drains juices into the Please note that these images are extracted from scanned page images that may have been digitally e
