Uterus, uterine tubes and ovaries
After going through the study unit, you will be able to:
- Identify the structures that make up the uterus, uterine tubes and ovaries
- Understand the anatomical relations of the uterus, uterine tubes and ovaries
- Discover the function of the uterus, uterine tubes and ovaries
Along with the vagina, the uterus, uterine tubes and ovaries represent the internal organs of the female reproductive system (female internal genitalia).
The uterus, also known as the womb, is a pear-shaped muscular organ situated in the pelvis anterior to the rectum and posterior to the urinary bladder. It is about 8 cm long and is divided into 4 parts - the cervix, isthmus, corpus, and fundus. The uterus has many functions, such as providing vaginal and uterine secretions, hosting the fetus during pregnancy, and allowing sperm to pass to the uterine tubes in order to fertilize an egg (ovum).
The ovaries are paired disc-shaped endocrine glands, responsible for the production of eggs (ova) and the secretion of the hormones progesterone and estrogen. An ovum is released every 3 to 4 weeks into the uterine tube, which is a paired, 10 cm long muscular tube. The uterine tube extends laterally from each side of the uterus, serving as a passageway between the ovaries and the uterus.

|Definition||Pear-shaped muscular organ, 8 cm long|
|Parts||Cervix, isthmus, corpus, and fundus|
Endometrium (innermost mucous membrane layer)
Myometrium (smooth muscle layer)
Perimetrium (serosa or outer serosal layer)
|Ligaments||Uterosacral ligament, broad ligament of uterus (mesometrium, mesosalpinx, mesovarium)|
|Relations||Vagina (inferior), urinary bladder (anterior), rectum (posterior), uterine tubes (left and right), ovaries (left and right)|
|Function||Provide vaginal and uterine secretions, host the fetus during pregnancy, allow sperm to pass through the uterine tubes in order to fertilize an egg, provide mechanical protection, nutritional support to the fetus, and remove waste from inside the uterus.|
