Plural form of endometrium; the inner linings of multiple uteruses or the tissue being discussed in plural contexts.
From 'endo-' (inner) and Greek 'metra' (womb/uterus). The plural 'endometria' follows the Latin-Greek convention for anatomical terminology used since the 17th century.
Using the plural 'endometria' in medical research allows doctors to compare tissue samples from multiple patients at once, which is especially important when studying diseases like endometriosis.
