!Uterus
!!Anatomical overview
The uterus or womb is the major female ((Reproductive - System Overview|reproductive organ)). It is pear-shaped and situated above the pelvis floor between urinary bladder and intestines. One end  the ((Reproductive - Uterus - Mouth and Neck|cervix))  opens into the ((Reproductive - Vagina|vagina)); the other is connected on both sides to the ((Reproductive - Fallopian Tubes|fallopian tubes)). The uterus consista of 3 layers: __perimetrium__ (a serous membrane), __((Reproductive - Uterus - Myometrium|myometrium))__ (a thick layer of smooth muscle) and __((Reproductive - Uterus - Endometrium|endometrium))__ (the inner lining).

The main function of the uterus is to accept a fertilized ovum which becomes implanted into the endometrium and derives nourishment from blood vessels which develop exclusively for this purpose. The fertilized ovum becomes an embryo, develops into a __fetus__ and gestates until childbirth. Due to anatomical barriers such as the pelvis, the uterus is pushed partially into the abdomen due to its expansion during pregnancy.

In birth the ((Organ Walls - Smooth Muscle Layer|smooth muscle)) press the fetus in peristaltic waves through the cervix and vagina. The Endometrium or __placenta__ is expelled after the baby.

Correction: there is no striated muscle in the cervix, but the wall consists of connective tissue (governed by the cerebral medulla) with longitudinal smooth muscle fibres.
