FEMALE REPRODUCTIVE SYSTEM The female reproductive system is designed to carry out several functions. It produces the female egg cells necessary for reproduction , called the ova or oocytes. The system is designed to transport the ova to the site of fertilization. Conception, the fertilization of an egg by a sperm, normally occurs in the fallopian tubes. The next step for the fertilized egg is to implant into the walls of the uterus, beginning the initial stages of pregnancy . If fertilization and/or implantation do not take place, the system is designed to menstruate (the monthly shedding of the uterine lining). In addition, the female reproductive system produces female sex hormones that maintain the reproductive cycle. Parts of the female reproductive system a. Broad Ligaments . Two wing-like structures that extend from the lateral margins of the uterus to the pelvic walls and divide the pelvic cavity into an anterior and a posterior compartment. b. Corpus Luteum . The yellow mass found in the graafian follicle after the ovum has been expelled. c. Estrogen . The generic term for the female sex hormones. It is a steroid hormone produced primarily by the ovaries but also by the adrenal cortex. d. Fimbriae . Fringes; especially the finger-like ends of the fallopian tube. e. Follicle . A pouch like depression or cavity.
