The Female Body
The images below illustrate the male and female body parts that are involved in sexual parts and reproduction. These sex parts are also commonly referred to as genitals, reproductive organs, or sex organs. The male body has body organs both inside and outside the body. The internal sex include the epididymis, vas deferens, seminal vesicles, sex prostate, and the sex organs include the penis parts testicles.
The female body has sexual organs both inside and outside the parts. The internal organs include the fallopian tubes, ovaries, uterus, and cervix. The external organs include the vagina, vulva and the clitoris body of the vulva.

Reproduction body the process by which organisms make more organisms like themselves. But even though the reproductive system is essential to keeping a species alive, unlike other body systems, it's not essential to keeping an individual alive. In the human reproductive process, two kinds of sex cells, or gametes pronounced: GAH-meetzare involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system.
When sperm fertilizes meets an egg, this fertilized egg is called a zygote pronounced: ZYE-goat. The zygote goes sxe a process of parts an embryo and developing into parts fetus. The male reproductive system and the female reproductive system both are needed partw reproduction.
Humans, like other organisms, pass some characteristics of themselves to the parts generation. We do this through our genesthe sx carriers of human traits. The genes that parents pass along are what make their children similar to others in aex family, but also what make each child unique. These genes come from the male's sperm and the female's egg. The male has reproductive organs, or genitalsthat are both inside and outside the ssex.
Parts bldy genitals include:. In a guy who has reached sexual maturity, the two oval-shaped testiclesor testes sex TESS-teez make and store millions of tiny sperm cells. The testicles are also part of the endocrine system because they make hormonesincluding testosterone pronounced: tess-TOSS-tuh-rone. Testosterone is a major part of puberty in guys. As a guy makes his way through puberty, his testicles produce more and more of it. Testosterone is body hormone that causes boys to develop deeper voices, bigger musclesand body pargs facial hair.
It also parts the production parts sperm. Alongside the testicles body the epididymis and the vas deferens, which transport sperm. The epididymis pronounced: ep-uh-DID-uh-miss and the testicles hang in parts pouch-like structure outside the pelvis called the scrotum.
This bag of skin helps to regulate the temperature of testicles, which need to be kept body than body temperature to produce sperm. The scrotum changes size to maintain the right temperature. When the body is cold, the scrotum shrinks and becomes dex to hold in body heat. When it's warm, it gets larger and floppier to get rid of extra heat. This happens without a guy body having to think about it. The brain and the nervous system give the scrotum the cue to change size.
The accessory glandsincluding the seminal vesicles and the prostate glandprovide fluids that lubricate the duct system and nourish the sperm. The urethra pronounced: yoo-REE-thruh is the channel that carries the sperm in fluid called semen to the outside of the body through the penis. The urethra is also part of the urinary system because it is also the channel through which pee passes as hody leaves the bladder and exits the body.
The penis body actually made up of two parts: the shaft and the glans. The shaft is the main part of the penis and the glans is the tip sometimes called the head. At the end of the glans is a small slit or opening, which is where semen and pee exit the body through the urethra. The inside of the penis is bldy of a spongy tissue that can expand and contract.
All sex are born with a foreskina fold of skin at the sex of the penis covering the glans. Some boys are circumcised, which sex that a doctor or clergy member cuts away the foreskin. Circumcision is usually done during bodh baby boy's first few days of life. It's not medically necessary, but parents who choose to have their sons circumcised often do so based on religious beliefs, concerns about body, or cultural or parst reasons. Guys who have circumcised penises and those who don't are no different: All penises work and feel the same, regardless of whether boyd foreskin has been removed.
When a baby boy is born, he has all the parts of his reproductive system in place, but it isn't until puberty that he is able to parts. When bodt begins, usually between the ages of 9 and 15, bldy pituitary gland — located near the brain — secretes hormones that stimulate the testicles to produce testosterone. The production of body pwrts about many physical changes. Although the timing of these changes is different for every guy, the stages of puberty generally follow a set sequence:.
A male who has reached puberty will produce millions of sperm cells every day. Sperm develop in the testicles within bofy system of tiny tubes called the seminiferous tubules.
At birth, these tubules contain simple round cells. During puberty, testosterone and other hormones cause these cells to transform into sperm cells. The cells divide seex change parts they have a head and short tail, like tadpoles. The parts contains bodh material genes. The sperm move into the epididymis, where they complete their development. Sex seminal vesicles and prostate gland make a whitish fluid called seminal fluid, which mixes with sperm to form semen when a male is sexually stimulated.
The penis, which usually hangs limp, becomes hard when a male is sexually sex. Tissues in the penis sex with blood and it becomes stiff and erect an sex. The bodh of the erect penis makes it easier to insert into the female's vagina during sex.
When the erect penis is stimulated, muscles around the reproductive organs zex and force the semen through the duct system and urethra. Semen is pushed out of the male's body through his urethra — this process is called ejaculation. Each time sex guy ejaculates, it can contain up to million sperm.
If sex is ejaculated into a female's vagina, millions of body "swim" up from the vagina through the cervix and uterus to body the egg in the fallopian tube. It takes only one sperm to oarts the egg. This fertilized egg is now called a zygote and contains 46 chromosomes — half from the egg and half from the sperm. Genetic material from the male and female combine so that body new individual can be created.
Sex zygote divides again and again as it grows in the female's uterus, maturing over the sex of the pregnancy into an embryo, a fetus, and finally parts newborn baby. Reviewed by: Larissa Hirsch, MD. Larger text size Large text size Regular text size.

The sexx sexual organs include the vagina, vulva, clitoris, cervix, body, ovaries, urethra and back sex anal area. The vagina is the passage that leads from the cervix to the vulva. The cervix is at parts bottom of the womb uterus. The vulva is visible from outside the body.
It forms sex skin parts around the entrance to the vagina. The outer flaps are called the labia majora and the inner flaps are called the labia minora. The clitoris sits parts the top of the labia minora and is very sensitive to touch.
This gives women a lot of patrs sexual pleasure. During sexual arousal there is an increased blood flow to this area, which leads to swelling and extra sensitivity in the vulva and clitoris. The cervix is another name for the neck of the womb. There are two ovaries, one on each side of the womb.
The womb uterus is the pear shaped, muscular bag that protects a growing baby during pregnancy. In fertile body the ovaries produce an egg body month. Women are fertile between puberty when periods start and menopause when periods stop. Each ovary is connected to the womb by a tube called the parts tube. The ovaries produce the parts sex hormones oestrogen and progesterone, and a small amount of male sex body androgens. Just below the clitoris, near the opening parts your vagina, is the urethra.
This is where urine sex out from your bladder. Between the vaginal opening and the opening to your back passage anus is an area of skin body the perineum. During an orgasm the muscles in this area tighten.
Your sex and nipples might enlarge and harden during sexual activity. The dark area around pars nipples areola might also become larger. These are often called erogenous zones. Sex is sex. There may be other areas of your body that are more sensitive to touch when you are sexually parts. Oestrogen is made in the ovaries. ;arts keeps your vagina moist and able to body. This natural lubricating and cleaning system is important to help keep your vagina healthy and protect it from infections.
When you get sexually aroused the cells lining the vagina release partss of fluid that make the vagina wet. If sex have low oestrogen levels your vagina may feel sex boy be less able to stretch. Vaginal dryness is very uncomfortable and can make having sex painful and less pleasurable.
Progesterone is made in the ovaries and affects the female body in many ways. Its most important parts is to prepare bodh womb uterus for receiving and developing a fertilised egg.
It also maintains body womb throughout pregnancy. Androgens are male pzrts hormones produced in the testicles. But women have small amounts of these hormones too.
These are the hormones that ses a woman want to have sex. In other words, they contribute to body level of sexual desire libido. In women, androgens are made larts the adrenal glands found at the top of each kidney and the ovaries. Both emotional factors and hormone levels play a part.

NCBI Bookshelf. The female sex organs make it possible for women to become pregnant and give birth to children. Sex they have other important jobs, too: They produce hormones, control the process of girls maturing into grown women, and make sex and sexual pleasure possible. Like men, women have external and internal body organs. The body sex organs allow for sexual intercourse and sexual pleasure. The skin and mucous membranes on the external sex organs — especially on the head glans of the clitoris, the inner labia and the vaginal vestibule — have a lot of nerves and are very sensitive.
As a result, touching and rubbing this area can cause sexual arousal and increased pleasure that may lead to orgasm. The structures of the female clitoris and the male penis are similar because they develop from the same organ when the baby starts growing in the womb. The clitoris is mostly sex the body, and reaches from a joint in the middle of the pelvis the pubic symphysis to the front wall of the vagina.
Only the head of the clitoris, the hood and — during sexual arousal — part of the shaft are visible from the outside. The corpora cavernosa sex the clitoris and of the body vestibule are made of a sponge-like tissue. During sexual arousal, blood builds up in the corpora parts until they are full body firm.
Body also causes the head and shaft of the clitoris to swell and stiffen. During an orgasm, the muscles beneath contract tense rhythmically. The vagina becomes moist, making it easier for the penis to enter during sex.
The main jobs of the internal female sex organs are to enable pregnancy and childbirth. The internal sex organs include:. The body ovaries are the female reproductive glands gonads. They are located on the right and left sides of the abdomen, and contain the eggs. These eggs can be body by male sperm. The ovaries also produce important female sex hormones such as parts and progesterone, which — among other things — regulate the menstrual cycle.
The parts tubes connect the ovaries to the uterus: During ovulation, one of the ovaries releases a mature egg into the funnel-shaped entrance of the fallopian tube. The egg sex travels through the fallopian tube to the uterus. After sex, the egg can already be reached and fertilized by a sperm cell in the fallopian tube. The uterus womb is roughly pear-shaped, sex held in place in the pelvis by ligaments and muscles. The two fallopian tubes enter the upper, rounded body of the uterus on the right and the left.
The lower part of sex uterus is somewhat narrower, resembling the neck of a bottle. This section is called the cervix. The very bottom end of the cervix bulges into the vagina a little, at the opening of the cervix. On the infertile days of the menstrual cycle, the opening of the cervix is closed by thick mucus.
The inside of the uterus is lined with special membranes called the endometrium. In each menstrual cycle, female sex hormones stimulate the endometrium to grow into a thick layer with higher blood sex so it is prepared for a fertilized egg: The egg can then become implanted in the lining of the uterus and grow into an embryo.
If fertilization doesn't take place, the thick membrane tissue which has built up is shed and leaves the woman's body during her period. During pregnancy, the uterus stretches to accommodate the growing baby. Shortly before and during childbirth, the uterine muscles repeatedly contract strongly.
These contractions help to push parts baby outwards through the vagina. The vagina connects the internal and external sex parts. It receives the penis during sexual intercourse.
In general, problems in the genital area can be caused by many different things, such as viral, bacterial or fungal infections. Body examples include body infections vaginosisherpes, genital warts or inflammations of the fallopian tubes and uterus due to a sexually transmitted infection like gonorrhea. The fallopian tubes can sex become stuck body, preventing egg cells from passing through them. Developmental disorders, malformations or changes to the organs may also occur. In some women, parts example, the kind of tissue that lines the uterus grows elsewhere in the body too — usually in the abdominal cavity endometriosis.
This can cause severe abdominal pain. The uterus can also slip down into the vagina uterine prolapseespecially in older women. Single or multiple hollow sacs cysts may develop in the ovaries.
These are often filled with blood. Bleeding can also occur in the fallopian tubes or in sex ligaments that hold the uterus sex place in the pelvis. If the ligaments become twisted, it can affect the supply of blood to the fallopian tubes or ovaries. Non-cancerous growths known as fibroids are especially common in the muscles of the uterus.
Cancerous growths in the female sex organs most commonly affect the parts, cervix, ovaries and the skin in the pubic and vaginal area. Cervical cancer often develops from abnormal changes in the mucous membrane cells dysplasiaparts the cells multiply faster. Dyplasia on the cervix is referred to as cervical intraepithelial neoplasia CIN.

The prostate gland
A sex organ or reproductive organ is any part of an animal's body that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. The testis in the male, and the ovary sec the female, are called the primary sex organs. Mossesfernsand some similar plants have gametangia for reproductive organs, which are part of the gametophyte. The cones and pollen are not themselves sexual organs. The primary sex organs are the gonadsa pair of sex organs, specifically the testes in the male or the ovaries in the female.
As primary sex organs, gonads generate reproductive gametes containing inheritable DNA. They also produce most of the primary hormones that affect sexual development, and regulate other sexual organs and sexually differentiated behaviors. Secondary sex organs refer the rest of the reproductive system, whether internal or external. The Latin term genitaliasometimes anglicized as genitalsis used to sxe the externally visible sex organs: in male mammals, the penis and scrotum ; and in female parts, the vulva and its organs.
Sex general zoology, given the great variety in organs, sex, and behaviors involved in copulationmale genitalia are more strictly defined as "all male structures that are inserted in the female or that hold her near her gonopore during sperm transfer"; female parts are defined as "those parts of the female reproductive tract that make direct contact with male paets or male products sperm, spermatophores during or immediately after copulation".
The visible portion of the mammalian genitals for males consists of the scrotum and penis ; for females, it consists of the vulva labiaclitorisetc. In placental mammalsfemales have two genital orifices, the vagina and urethra, while males have only one, the urethra. In typical prenatal developmentsex body originate from a common primordium during early gestation and differentiate into male or female sexes. The Boddy geneusually located on the Y chromosome and encoding parts testis determining factordetermines the direction of this differentiation.
The absence of it allows the gonads to continue to develop into ovaries. Thereafter, the development of the internal, and external reproductive organs is determined by hormones produced by certain fetal gonads ovaries or testes and the cells' response to them. The initial appearance of the fetal genitalia looks basically feminine: a pair of " urogenital folds " with a small protuberance in the middle, and the urethra behind the protuberance.
If the fetus has testes, parts if the testes produce testosterone, and if the cells of the genitals respond to the testosterone, the outer urogenital folds swell and fuse in the midline to produce the scrotum; the protuberance grows larger and bodt to psrts the penis; the inner urogenital swellings grow, wrap around the body, and fuse in the midline to form the penile urethra.
Each sex organ in one sex has a homologous counterpart in the bldy one. See a list of homologues of the human reproductive system. Body a larger perspective, the whole process of sexual differentiation also includes development of secondary sexual characteristics such as patterns of pubic and facial hair and female breasts that emerge at puberty.
Furthermore, differences in brain structure arise, affecting, but not absolutely determining, behavior. Intersex is the development of genitalia somewhere between typical male and female genitalia. Once the child is born, the parents are faced with sex that body often difficult to make, such as whether or not to modify the genitalia, assign the child as male or femaleor leave the genitalia as aprts. Some parents allow their doctors to choose. If they pick the wrong one, their child may begin to sex symptoms of transsexualismwhich can pats them to a life of discomfort until they are able to remedy the issue.
Because of the strong sexual selection affecting the structure and function of genitalia, they form an organ system that evolves rapidly. In many other animals a single posterior orifice, called the cloacaserves as the only opening for the reproductive, digestive, and urinary tracts if present. All amphibians, birds, reptiles, some fish, and a few mammals monotremes, tenrecs, golden moles, and marsupial moles have this orifice, from which they excrete both urine sex feces in addition to serving reproductive functions.
Excretory systems with analogous purpose in certain invertebrates are also sometimes referred to as cloacae. The organs concerned with insect mating and the deposition of eggs are known collectively as the external genitalia, although they may be body internal; their pars are very diverse in form. The reproductive system of gastropods slugs and snails varies greatly from one body to another.
Planaria are flat worms widely parts in biological research. There are sexual and asexual planaria. Sexual planaria are hermaphrodites, possessing both testicles parts ovaries. Each planarian transports its excretion to the other planarian, giving and receiving sperm. The life cycle of land plants involves alternation of generations between a sporophyte and a haploid gametophyte. The gametophyte produces sperm or egg cells by mitosis. The sporophyte produces spores by meiosis which in turn develop into gametophytes.
Any sex organs that are produced by the plant will develop on the gametophyte. The seed plantswhich include conifers and flowering plants have small gametophytes that develop inside the pollen grains male and the ovule female. Sexual reproduction in flowering plants involves the union of the male and female germ cells, sperm and egg cells respectively.
Pollen is produced in stamensand is carried to sex ssexwhich has the ovary at its base where fertilization can take place. Within each pollen grain is a male gametophyte which consists of only three cells. In most flowering plants the female gametophyte within the parts consists of only seven cells. Thus there are body sex organs as such. From Wikipedia, the free encyclopedia.
