Ovaries are pair of small glands similar to almonds, and located in the lateral and superior parts of the uterus. They produce hormones (estrogen and progesterone) and ova, "eggs", or gametes. In fertility lifetime, every month during ovulation, a mature egg is released and travels from the ovary to the fallopian tube, where it might be fertilized before reaching the uterus. Uterus is a hollow muscular organ; it is pear-shaped in posterior and superior to the bladder. The uterus or womb is connected to the two fallopian tubes on the superior end and to the vagina on the inferior end. The lining of the uterus, endometrium supports to the embryo during early stage of development.
Vagina is an elastic, muscular tube between the uterus and the exterior. The vagina functions as the repository for the penis in sexual intercourse; it transfers sperm to the uterus and fallopian tubes, and it is a canal that …show more content…
Ovulation is under the influence of FSH and LH, follicle stimulating hormone and luteinizing hormone; therefore the ovary produces an ovum in the process of ovulation and it takes about a week for the ovum to travel to the uterus.
Pregnancy: If sperm reaches and penetrates it, the ovum becomes a zygote, a fertilized zygote, with a full complement of DNA and genetic patrimony inside it.
In about two-week of cell division, the zygote forms the embryo which nests itself into the uterine endometrium wall, and begins to form a cavity for amniotic fluid, umbilical cord, and then placenta. In the first 8 weeks, the embryo will form most of the tissues and organs of the adult, and then the fetus grows larger and becomes more complete.
Menstruation: If the ovum is not fertilized or if it fails to implant into the wall of uterus, the arteries of the uterus constrict to shut the blood flow off to the endometrium which causes the death of wall cells and eventual shedding of tissue, or
