Emulgent
EMULG'ENT, adjective [Latin emulgeo; e and mulgeo, to milk out.]
Milking or draining out. In anatomy, the emulgent or renal arteries are those which supply the kidneys with blood, being sometimes single, sometimes double. The emulgent veins return the blood, after the urine is secreted. This the ancients considered as a milking or straining of the serum whence the name.
