The story of the word

Galen's medicine ran on χυμοί, the humours, and both chyme and chyle come out of that vocabulary before later anatomists split them into stomach output and lymph. The root verb is χέω, to pour, which also stands behind ecchymosis, blood poured out under the skin, and parenchyma, tissue poured in beside. Physiologists reserve chyme strictly for the acid slurry leaving the pylorus and call nothing else by the name.
