Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which digestive system part matches the description:secretes digestive enzymes into the duodenum, the first segment of the small intestine
A
stomach
B
small intestine
C
pancreas
D
liver
Explanation: 

Detailed explanation-1: -The pancreas secretes digestive enzymes into the duodenum and hormones into the bloodstream. The digestive enzymes (such as amylase, lipase, and trypsin) are released from the cells of the acini and flow into the pancreatic duct.

Detailed explanation-2: -Your pancreas creates natural juices called pancreatic enzymes to break down foods. These juices travel through your pancreas via ducts. They empty into the upper part of your small intestine called the duodenum. Each day, your pancreas makes about 8 ounces of digestive juice filled with enzymes.

Detailed explanation-3: -Your stomach, small intestine and pancreas all make digestive enzymes. The pancreas is really the enzyme “powerhouse” of digestion. It produces the most important digestive enzymes, which are those that break down carbohydrates, proteins and fats.

Detailed explanation-4: -Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen. Parietal cells within the stomach lining secrete hydrochloric acid that lowers the pH of the stomach. A low pH (1.5 to 2) activates pepsin.
