Hemiatresia of the vagina, uterus
**Hemiatresia** is partial or complete fusion of a single part of an organ. Such paired organs are, for example, the human nose: the Eustachian tube (one nostril of a person), the posterior ear (another); the uterus, in section resembling the letter “Y” - the entrance to the fallopian tubes (cervix), the main (uterine) openings (body), the lateral horns (divided uterine bodies). These organ formations are paired and are so-called bi- and multilateral. In a certain sense, some other organs are also bilateral
