The size and position of the uterus vary with age, menstrual cycle, and parity. On ultrasound measurements, the Normal size of the uterus is from 7 cm to 9 cm in patients with multiple pregnancies, and about 4 cm to 5 cm wide.
The uterus is divided into three parts: the fundus, the body and the cervix.
The uterine cavity is lined by the endometrium which is formed by a mucous membrane. The endometrium undergoes monthly cyclical changes, this process is called menstrual cycle , this cycle occurs in response to hormonal stimulation and in preparation for an implantation in case a fertilized egg gets to the cavity, The uterus is suspended in the middle of the pelvic cavity by the broad ligament that anchors it to the pelvic sidewalls.

to facilitate the transport and provide nutrients to the ova and spermatozoa.
to act as the site for fertilization, the process that occurs specifically at the ampullary portion.
to transport the zygote (fertilized egg) into the uterine cavity and to provide nutrients on the way.
Note: Fallopian tubes are not seen on ultrasound unless there is fluid or blood inside which is considered abnormal.
The almond shape glands, one on each side, vary in size and position with age, menstrual cycle, parity, and degree of distention of the surrounding organs.
