Having the quality of emulging or extracting; relating to or promoting extraction or drainage, especially in medical contexts.
From Latin 'emulgens' (milking out), this adjective entered medical English to describe substances or processes that extract or draw out materials.
The 'emulgent arteries' are blood vessels near the kidneys that were named by anatomists who saw them as 'milking' waste products from the blood—a poetic name for what we now call the renal arteries.
