A protein based layer called the zona pellucida helps protect the egg. (educational-portal.com) The function is to carry a set of chromosomes from the female and starts fertilization by the sperm. A problem with the ovum is a blighted ovum. That is the failure to develop early embryotic death. The vagina is a muscular flexible tissue that is the sex organ and also known as the birth canal.
Uterus is the organ in the lower body of a women or female mammal where offspring are conceived and in which they gestate before birth; the womb. Cervix is a narrow like passage forming the lower end of the uterus. Fallopian tube is either of a pert of tubes along which eggs travel from the ovaries to the uterus. Ovary is a female reproductive organ in which ova or eggs are produces, present in humans and other vertebrates as a pair. Estrogen is a group of steroid hormones that promote the development and maintained of female characteristics of the body.
There are two ovaries which are suspended by ligaments in the upper pelvic cavity either side of the uterus. Their function is to produce the hormone oestrogen and progesterone and to produce ova. What causes follicles to develop and what do they become? Each immature ovum is encased in a sac and the whole structure is called a follicle. The follicles develop, usually one at a time, in response to the various sex hormones until they become primary follicles.
The main parts of a female reproductive system are the ovaries, the oviducts (also called the fallopian tubes), uterus (womb), vagina, vulva and the breasts (where the milk for the baby is released). The ovaries are called "egg glands". They store tiny eggs called ova. These will develop into a baby, if a man's sperm fertilizes them. The ovaries also produce hormones.
It contains a complete set of the genetic information necessary for the development of a baby. Half of that genetic material comes from the mother, carried in the egg; the other half comes from the father, carried in the sperm cell. That means the baby will have a combination of characteristics from both parents. The next step after fertilization consists of the fertilized cell floating down the fallopian tube toward the uterus, where the cell divides into two. Those two cells then divide to make four, and the division continues.

Once puberty is achieved in females, hormones allow the reproductive system to create mature ova or eggs. In the female body, two white ovaries are present in the uterus, one is located on the left side, and the other is located on the right side. Located inside the ovaries are egg cells and when the female reaches puberty, her egg cells will begin to mature each month. Once they are developed, they will be discharged and enter the fallopian tube. As it is traveling through the tube, it is susceptible to being fertilized by a sperm cell through coitus.
The system’s internal structures are the vagina, uterus, ovaries, and fallopian tubes. The uterus is responsible for holding and nourishing a fetus while it develops during a nine month term. The ovaries are the structures that make it possible for a woman to reproduce; they produce eggs that can then be fertilized by sperm as well as secrete hormones. The fallopian tubes are narrow tubes that are attached to the upper part of the uterus and serve as tunnels for the ova (egg cells) to travel from the ovaries to the uterus. Conception, the fertilization of an egg by a sperm, normally occurs in the fallopian tubes.
In the next phase of Meiosis, Meiosis II, the two cells split, again, forming four cells also consisting of 23 chromosomes, and the cell undergoes the change in order to perform its more specialized function for reproduction. This production takes place in the male gonads, also known as the testes. Oogenesis Oogenesis, also called ovigenesis, is the process in which the female anatomy produces egg cells. The egg cell is made up of three layers: a jelly coat, the vitelline layer, and the egg cell’s plasma membrane. A hormone called gonadotropin releasing hormone, or GnRH, control the production of the follicle-stimulating hormones and the leutinizing hormones that, as stated above, are also found in the male body.
