What is the term for producing a substance within an organ and discharging it?

Explanation:
Secretion is the production of a substance within a gland or organ and its release, typically through a duct or into a lumen where it’s needed. In the digestive system, glands like salivary glands, the stomach, pancreas, and liver generate enzymes, acid, mucus, bile, and other products and secrete them into the digestive tract. This differs from absorption (taking substances into the bloodstream), elimination (removing waste from the body), and ingestion (taking in material by mouth). So the phrase “producing a substance within an organ and discharging it” best fits secretion.
