When looking at a diagram of the female reproductive system from the front, the uterus is in the middle between the two fallopian tubes and above the cervix and vagina, according to WebMD. It is shaped somewhat like an upside-down pear.
The uterus is the organ that houses the fetus if an egg becomes fertilized, according to WebMD. In a normal reproductive system, a woman has two ovaries and two fallopian tubes, which are the rope-like entities protruding from the sides near the top of the uterus, according to WebMD. Each month, one of the ovaries releases an egg into the corresponding fallopian tube; the egg is either fertilized and implanted in the uterus to grow into a fetus, or it is passed out through the vagina during a woman's monthly bleeding, notes InnerBody.
