Patient's question:
No.Doctor's answer:
The uterus is the organ that produces menstruation and carries a fetus, located in the central part of the pelvic cavity between the bladder and rectum. The size of the uterus is related to age and fertility. In nulliparous women, it is approximately 7.5 cm long, 5 cm wide, and 3 cm thick. The uterus can be divided into three parts: the fundus, the body, and the cervix. The uterine cavity is inverted triangular in shape, about 6 cm deep, with the upper two angles being the "uterine horns," which connect to the fallopian tubes. The lower end narrows into the "isthmus," which is about 1 cm long. During pregnancy, the isthmus gradually expands and forms the lower segment of the uterus during labor.
