The uterus, or womb, is the female organ that carries the fetus. When a woman becomes pregnant, fertilization normally takes place in the fallopian tube; next the fused egg and sperm travel to the lining of the uterus, implant and grow. Menstruation is the monthly shedding of the uterine lining; the monthly flow is composed of blood and tissue from inside the uterus that flows from the uterus through the cervix and out of the body through the vagina.
The uterus, commonly called the womb, is where an unborn baby grows during pregnancy. Typically, fertilization takes place in the fallopian tube and then the egg and sperm, now fused, travel to the uterine lining to implant and grow.
If pregnancy does not occur, the lining is shed in the monthly menstruation or period. The blood that flows out of the body is part blood and part tissue from the inside of the uterus. It goes from the uterus through the cervix and out out of the body through the vagina.
