The parts of the female reproductive system are the gametes, that is, a mature haploid germ cell, male or female, capable of uniting with another of the opposite sex in several reproductions to form a zygote . Egg is a person who possesses a specified amount. The ovum is a mature female reproductive cell, especially of a human or other animal, that divides to give rise to an embryo, usually only after fertilization by a male cell. The vaginalis is a muscular tube that leads from the external genitalia to the cervix of the uterus in women and most female mammals. The labia are the inner and outer folds of the vulva, on both sides of the vagina. The clitoris is a small, sensitive, erectile part of the female genitalia located at the anterior end of the vulva. The urethra is a tube through which urine is conveyed out of the body by the bladder and which in male vertebrates also carries sperm. The hymen is a membrane that partially closes the opening of the vagina and whose presence is traditionally considered a sign of virginity. The uterus is the organ in the lower part of the body of a woman or female mammal in which children are conceived and in which they gestate before birth; the maternal womb. The cervix is ​​a narrow passage that forms the lower end of the uterus. The fallopian tubes are a series of tubes along which eggs travel from the ovaries to the uterus. The ovary is a female reproductive organ in which eggs are produced, found in pairs in humans and other vertebrates. Estrogens are a group of steroid hormones that promote the development and maintenance of feminine characteristics in the body. Progesterone is a steroid hormone released by the corpus lutetium that stimulates the uterus to prepare for pregnancy. The parts of the male reproductive system are the testes, which are an organ that produces sperm... middle of paper... in an organic fluid. Sperm is made up of 3 main parts: the head, the midsection and the tail. The length is 10 microns. The prostate is a gland the size of a walnut. The urethra is a narrow fibromuscular tube that carries urine and semen from the bladder and ejaculatory ducts. The penis is a cylinder-shaped male external sexual organ. The glans is the sensitive bulbous structure at the distal end of the penis. Inside the testes are the seminiferous tubules. It is also made up of the germinal epithelial cell which forms three layers. The seminal vesicles have a paired, highly coiled tubular structure. It is a hollow, expandable and muscular organ. Located above the prostate and behind the urinary bladder.FunctionThe parts of the female reproductive system function. The egg/ovum must carry the set of chromosomes contributed by the female. It creates the right environment to allow fertilization by sperm .
