The uterus is divided into two parts: the cervix, which is the lower part that opens into the vagina, and the main body of the uterus, called the corpus. Approximately half its length is visible, the remainder lies above the vagina beyond view.
Fallopian tubes - Uterine tubes which transport egg cells from the ovaries to the uterus. Interspersed between the ciliated cells are peg cells, which contain apical granules and produce the tubular fluid that contains nutrients for spermatozoa, oocytes, and zygotes.
A very thin piece of skin-like tissue called the hymen partly covers the opening of the vagina. Reproductive System and Disease The reproductive system can be impacted by a number of diseases and disorders. The uterus is a pear-shaped muscular organ.

The uterus is mobile and moves under the pressure of the full bladder or full rectum anteriorly, whereas if both are full it moves upwards. They produce, store, and release eggs into the fallopian tubes in the process called ovulation pronounced: av-yoo-LAY-shun. During menopause, the female reproductive system gradually stops making the female hormones necessary for the reproductive cycle to work.
