The fluid or nutritive substance present within the blastocele of an early embryo.
From Greek 'blastos' (bud, embryo) + 'chyle' (from 'chylos,' juice, fluid). Literally means 'bud juice' or 'embryo fluid.'
This word is pure poetry—scientists observed nourishing fluid inside the embryonic cavity and literally called it 'bud juice,' showing how scientific terms often describe exactly what you're looking at!
