The digestive organs which release enzymes into the small intestine are the pancreatic acini and the intestinal wall itself. Gallbladder also releases bile juice for small intestine but no digestive enzyme is present in it.


The digestive organs that release juices into the small intestine are the pancreas and the gallbladder.

The pancreas makes many enzymes such as:

#1.# pancreatic amylase
#2.# pancreatic lipase
#3.# peptidases
#4.# trypsin
#5.# chymotrypsin

Pancreatic amylase helps digest starch and glycogen into maltose, a disaccharide.

Pancreatic lipase helps digest lipids into glycerol and fatty acids.

Peptidases help digest peptides into smaller peptides and amino acids.

Trypsin and chymotrypsin are proteases which help digest peptides into smaller peptides.

The liver produces bile, which is then stored in the gallbladder between meals. When required, the bile ducts located beneath the gallbladder will allow bile to flow into the duodenum, the first section of the small intestine.

Bile contains a special component, bile salts, which helps break down fat droplets into smaller fat droplets. This increases the surface area of the fat droplets so that fat digesting enzymes can more easily break down the fats in the small intestine.

Enzymes secreted by intestinal glands are lipase, amylase, sucrase, lactase, maltase, aminopeptidase, carboxypeptidase, etc.
