Which term describes the release of secretions into the digestive tract?

Explanation:
Secretion refers to the release of substances into the digestive tract to aid digestion. Glands produce and pour out fluids like saliva, gastric juice, bile, and pancreatic enzymes directly into the digestive lumen, which helps break down food as it moves through the tract. This is distinct from ingestion, which is simply taking food into the mouth; absorption, which is the uptake of digested nutrients into the bloodstream or lymph; and elimination, which is the expulsion of indigestible waste from the body. So secretion is the best fit because it specifically describes releasing digestive secretions into the tract to facilitate digestion.
