Small Intestine

 Chemical digestion of fats begins in the small intestine.
 Chyme enters the upper portion of the small intestine called the

duodenum.
 This causes the gallbladder to contract and secrete bile into the

duodenum through the bile duct.
 The pancreas then secretes bicarbonate ions and enzymes.
 Bicarbonate ions neutralize the pH of the chyme.
