REPRODUCTIVE SYSTEM FUNCTIONS ➢ The major function of the reproductive system is to make sure that the human species survives. ➢ It is not necessary for every human being to produce children, but in order to continue our human species, at least some people have to have children. ➢ The four main functions of the human reproductive system are: • To produce egg and sperm cells, • To transport and sustain these cells, • To nurture the developing offspring, and • To produce hormones. MAJOR ORGANS ➢ In the human reproductive system, the major organs include the external genitalia and many internal organs including gonads producing gametes and hormones. ➢ These hormones are …show more content…
➢ In each tube is a sewing needle size passageway. At the other end of each fallopian tube is a fringed area that looks like a funnel and wraps around the ovary. The fallopian tube does not completely attach to the ovary. ➢ When an egg pops out of an ovary, it enters the fallopian tube and tiny hairs in the tube's lining help push it down the narrow passageway toward the uterus. After intercourse, sperm in the vagina passes through the cervix, the uterus, and then to the fallopian tubes. If a sperm encounters an ovum (egg), conception occurs. 4. Ovaries ➢ The female has two oval-shaped organs, called ovaries, that lie to the upper right and left of the uterus. ➢ The ovaries produce, store, and release eggs into the fallopian tubes during the process called ovulation. ➢ Each ovary measures about 1 1/2 to 2 inches in a grown woman. The ovaries are part of the endocrine system and produce estrogen and progesterone, female sex hormones. ➢ The ovaries are among the first organs to be formed as a female baby develops. By 20 weeks, the ovaries have about 6 to 7 million potential egg cells. From that point on however, the number begins to decrease rapidly. A newborn infant has between 1 million to 2 million egg cells. By puberty, the number of egg cells remaining is about 300,000. For every egg that matures and undergoes ovulation, roughly a thousand will fail. During the course of an average
The next step in this cycle is ovulation. Ovulation is when a small egg travels down the fallopian tube that goes in the uterus to make lining with extra blood and tissues in order to prepare for

Each month inside your ovaries, a group of eggs starts to grow. Eventually one of the eggs erupts from the follicle and this is known as ovulation. It usually happens about two weeks before your next period. A hormone is released that helps thicken the lining of your uterus, getting it ready for the egg. After the egg is released, it
Conception also known as fertilisation is the fusing of two gametes. This creates an embryo which will eventually develop into a baby. All human life begins with conception. A fertile woman will usually produce one egg a month around 2 weeks after the last menstrual period.
They extend about 4 inches laterally from either sides of the uterus to the ovaries. It is in the fallopian tubes that fertilization normally occurs. The tube transports the ovum, or egg, from an ovary to the uterus, but the tubes do make direct contact with the ovaries.
The ovaries are a pair of organs in the female reproductive system located on the lateral walls of the female pelvic cavity. Martini, Nath & Bartholomew,(2014)
eggs will essentially mature. Contrary to women, a man begins producing sperm at puberty, which gradually decreases along with age. During the actual conception, over 200 million sperms head towards the egg and try to break through. One is successful, the rest aren’t.
The Female Reproductive System structures are the egg / ovum. Its created and stored inside the ovaries. The vagina is an elastic, muscular tube that connects the cervix of the uterus to the exterior of the body. The uterus is a hollow, muscular, pear-shaped organ located posterior and superior to urinary bladder. The Fallopian tubes are a pair of muscular tubes that extends from the left and right superior corners of the uterus to the edge of the ovaries. The ovaries are a pair of small glands about the size
Forms the external body covering; protects deeper tissues from injury; synthesizes vitamin D; location of cutaneous receptors (pain, pressure, ect.) and sweat and oil glands.
Some disadvantages of sexual reproduction are as follows. Sexual reproduction cannot be done without a mate. Females want to mate with the best males who are strong and on top of the hierarchy. This can take lots of time and effort to find. It can even take years for an offspring to come out of mating for the female. The successful genes of an individual are being split up into a combined form with another individual's and it is not always guaranteed that the offspring of these two successful organisms will come out successful. Sexual reproduction is less reliable since fifty percent of these new combinations end up failing. When organisms mate, they are distracted by the pleasure they are giving to each other. All the ruckus and noises will attract predators and is also a disadvantage.
The ovary, or female gonad, is one of a pair of reproductive glands in women.
Do you know how you were born? Do you know how you came to be? The reproductive system is the system that made that all possible. Without the reproductive system you wouldn’t have been born. In order to produce offspring, the male and female reproductive systems have to be different. Each system has different parts, problems and care. Each system have different purposes, the male reproductive system’s function is to produce sperm, while the female reproductive system’s function is to produce ova, store ova and house a fertilized egg.

The reproductive system is questionably the body system that is the most important influence on life as we know it. It is the w ay in which we procreate and ensure our existence as a species. However, the penis is only one part of the male reproductive system, which constitutes of a series responsible for generating, storing, and transporting the genetic material contained in the sperm cells. The main organs include: testicles (or testes), the epididymides, the vas deferens, the ejaculatory duct, the urethra, and the penis. Others are the scrotum, urogenital opening, and the prostate gland.
