Limited digestion begins when salivary gland secretions enter the mouth. The enzymes in the saliva, such as amylase, start breaking down carbohydrates in the food. This initial digestion helps to start the process of breaking down the food particles into smaller, more easily digestible components.
The secretions of the pancreas join with bile from the liver to enter the duodenum. These secretions contain enzymes that aid in the digestion of fats, carbohydrates, and proteins.
The enzyme found in the mouth that breaks down starch is called amylase. Specifically, salivary amylase, produced by the salivary glands, initiates the digestion of starch into simpler sugars like maltose as food is chewed and mixed with saliva. This enzymatic action is crucial for the effective digestion of carbohydrates before they enter the stomach.
The intestinal mucosa produces most of the secretions that enter the small intestine (the mucosa of the small intestine produces secretions that primarily contain mucus, electrolytes, and water). The secretions of the liver and the pancreas also enter the small intestine and play essential roles in the process of digestion.
Secretions from the liver (bile and enzymes) will pass through the common hepatic duct and reaches the pancreatic duct. pancreatic juices from the pancreas will also flow to the pancreatic duct. both will be flowing to the duodenum through a small opening in the duodenum.
Salivary glands produce a clear liquid which moistens food as it is being chewed. Without moisture the food is like chewing sand. The glands also produce an enzyme. Most people, but not all, produce an enzyme called salivary amylase which begins to break down starches/complex carbohydrates before they enter the stomach. A test to see if you have this enzyme is to hold a piece of bread or rice cake..in your mouth and see if you sense a sweeter taste. If you have salivary amylase, the starch will become sugar in your mouth.

yes
the merocrine duct. and secretes in the "duct"
I'm unable to display images. However, the duodenum is the first part of the small intestine where bile and pancreatic secretions enter through the hepatopancreatic sphincter, also known as the sphincter of Oddi. This sphincter regulates the flow of bile and pancreatic juices into the duodenum for digestion.
