Because it will digest the proteins that are in the food chyme that enters into the small intestine and break it into smaller molecules that can be absorbed into the body in the jejunum.
Trypsinogen, chymotrypsin, and carboxypeptidase But, these are all released from the pancreas in the form of enzyme precursors, & none is fully active until it reaches the small intestine - otherwise they would be digesting the pancreas itself; enterokinase, released from the intestinal lumen, starts the chain of activation, so that for example, trypsinogen becomes the active enzyme trypsin.
longitudinal muscle
It controls entry of bile and pancreatic juice into the intestinal lumen
Bile is produced in the liver, and stored in the gallbladder. While eating, it is discharged into the lumen of the duodenum.
Pancreatine.
The subcutaneous oil glands in the scalp secretes via holocrine. Holocrine indicates a membrane rupture which destroys the cell and results in the secretion into the lumen.
Carbohydrates are the rapid energy foods, they are fragmented inside the intestinal lumen before they are absorbed into the blood or lymphatic system.
saline laxative a salt administered in hypertonic solution to draw water into the intestinal lumen by osmosis, distending it and promoting peristalsis and evacuation.

Lumen
The pancreatic duct comes from the pancreas to the small intestine as does the accessory pancreatic duct. Pancreatic juice containing important buffers and digestive enzymes travels through these ducts into the lumen or hollow part of the duodenum or first part of the small intestine. Physically, there is some connective tissue that holds both the pancreas and small intestine in place and near each other.
Double-lumen PICC lines come in two colors. Red is the blood access lumen or arterial lumen and blue is the blood return lumen or venous lumen. Despite the names, neither lumen is leads to an artery, but both lead into a vein.
