Question

Which set of components mixes with the food in the small intestine?

• A. Saliva, gastric juice, bile
• B. Gastric juice, bile, pancreatic juice
• C. Bile, pancreatic juice and saliva
• D. Bile, pancreatic juice, succus entericus

Answer 1

The correct option is D Bile, pancreatic juice, succus entericus

The pancreatic juice consists of enzymes, mucus and salts, the enzymes being amylase or amylopsin, trypsin and lipase or steapsin. The bile from the liver is a greenish-brown secretion and consists of mucus, bile acids, bile salts and bile pigment. The succus entericus consists of four important enzymes - invertin, maltase, lactase and enterokinase. The three digestive juices just described - pancreatic juice, bile, and succus entericus - are all mixed with food, which passes into the duodenum from the stomach and produces chemical changes as the food passes through the duodenum and jejunum.
