IPA: //trænspəˈlɛntəl//
KK: /trænspəˈleɪntl/
Relating to something that passes through or occurs across the placenta, often used in medical contexts.
The doctor explained the risks of a transplacental infection during pregnancy.
Transplacental → It is formed from "trans-" (meaning across) and "placenta" (from Latin *placenta*, meaning cake or flat object, which refers to the organ that nourishes the fetus). The word "transplacental" means across or through the placenta, indicating something that occurs or is transferred through this organ.
Think of something moving 'across' ('trans-') the 'placenta' — that's why transplacental refers to processes that happen through the placenta.
