Placenta

/pləˈsɛntə/noun

The organ that develops in the womb to feed and oxygenate the growing fetus.

The Greek roots

πλάξ
pláx
flat plate
+
πλακόεις
plakóeis
flat, cake-like

Literally: flat cake

The story of the word

Realdo Colombo named the organ in 1559 placenta uterina, the uterine cake, because that is what it looks like laid flat. Latin placenta was a genuine cake, a Roman flat pastry, and Rome had borrowed the name from Greek πλακόεντα, from πλάξ, a flat slab. So one of the more consequential organs in human biology carries a baker's word, twice removed.
