Etymology
the word placenta has a surprisingly domestic origin. it entered english directly from latin, where 'placenta' meant a type of flat cake. this latin term was itself a borrowing from the greek 'plakoús', meaning a flat, broad slab or cake. the anatomical term was coined in the 17th century by the anatomist realdo colombo, who noted the organ's resemblance in shape to a round, flat cake. this metaphorical naming based on physical appearance illustrates how scientific vocabulary often draws from familiar, everyday objects to describe new biological structures.
