Anatomical model of the female reproductive organs during pregnancy (embryo at two months). At two months of pregnancy, the womb has reached the size of an orange; the embryo measures about 3 cm and weighs 1 g. Its main organs are now developed (organogenesis) and its outward appearance is more refined (morphogenesis). Its limbs have lengthened and now end in fingers and toes. The neck and the face have formed as well as the eyes, eyelids, lips and ears. Differentiation of the internal reproductive organs has taken place. The embryo (10) floats in the amniotic fluid that fills the amniotic cavity (12). The latter is surrounded by a membrane, the amnion (11, white). The embryo is linked to the chorion (8a, mauvish grey, beginning to mature into the placenta) through the umbilical cord (9). The uterine cavity (13) is surrounded by the decidua, tissue resulting from transformations in the uterine endometrium (7). The decidua is divided into basal (8b, red, between the chorion and the womb), capsular (surrounding the embryo) and parietal deciduas (not in contact with the embryo). The last two elements have merged at this stage of pregnancy. The chorion entirely surrounds the amnion, lining the capsular decidua (not visible here). The infundibula (4, red) of the Fallopian tubes, bordered with fringe-like structures, are situated over each ovary (yellow). The latter are connected to the womb through their own specific ligaments. Each Fallopian tube is linked to a duct (pink) leading to the interior of the uterine cavity.
