The ovary is the gland responsible for the production of female sex hormones and ovules. In the pelvic cavity there are two ovaries, one on each side of the uterus, connected through the fallopian tubes.
The ovum is the female sexual cell released monthly by one of the ovaries in order to be fertilized by a sperm. It is one of the largest cells in the body.
The fallopian tubes are two muscular ducts that connect the ovaries with the uterus. Each one is approximately 4 inches long. It is here where the ovule is fertilized with the sperm.
The uterus is the organ of the female reproductive system where most of the pregnancy process occurs. It is characterized for being a hollow body, shaped like a pear, where the egg is implanted and the fetus develops. The fallopian tubes connect to the upper part of the uterus and the cervix at the lower end connects with the vagina.
The cervix is the lower part of the uterus that connects with the vaginal canal. The sperm can pass through it into the uterus looking for fertilization. The cervix allows bleeding from menstruation to go down into the vagina.
Endomtrium is a mucous membrane that covers the inside of the uterus. During the menstrual cycle it thickens in preparation of a possible implantation of an embryo. This lining is renewed in each menstrual cycle. If there is no fertilization, the endometrium disintegrates and is expelled from the body through menstruation.
