Anatomical model of the female reproductive organs during pregnancy (fetus at three months). At three months of pregnancy, the womb has reached the size of a grapefruit; the fetus measures approximately 10 cm and weighs 45 g. All the organs are in place and will continue to grow and develop. Sexual differentiation is visible. The fetus (10) floats in the amniotic fluid that fills the amniotic cavity (12). The latter is surrounded by a membrane, the amnion (11, white), which is linked to the chorion. The fetus is linked to the placenta (8a and b) by the umbilical cord (9). The placenta is divided into two main parts, a fetal surface, made of fetal tissue (8a, the chorion, mauvish grey), and a maternal surface (8b, the basal decidua, red). The uterine endometrium (7) is lined its inner surface by a mucous membrane, the decidua (14, red) that will be shed along with the placenta at parturition. The infundibula (4, red), bordered with fringe-like structures, of the Fallopian tubes are situated over each ovary (yellow), which itself is connected to the womb through its own specific ligament. Each Fallopian tube is linked to a duct (3, pink) leading to the interior of the uterine cavity. At the cervix (2), a residual vestige of the uterine cavity remains (1), that has elsewhere been deplaced by the fetus and the embryo-fetal membranes.
