Human reproductive system , organ system by which humans reproduce and bear live offspring.

The reproductive system of an organism, also known as the genital system , is the biological system made up of all the anatomical organs involved in sexual reproduction. Many non-living substances such as fluids, hormones , and pheromones are also important accessories to the reproductive system. These differences allow for a combination of genetic material between two individuals, which allows for the possibility of greater genetic fitness of the offspring. In mammals, the major organs of the reproductive system include the external genitalia penis and vulva as well as a number of internal organs, including the gamete -producing gonads testicles and ovaries. Diseases of the human reproductive system are very common and widespread, particularly communicable sexually transmitted diseases.

These organs do the following jobs within your body:. The male reproductive system is made up of internal inside your body and external outside your body parts. Together, these organs help you urinate rid your body of liquid waste materials , have sexual intercourse and make children. Most of the male reproductive system is located outside of your abdominal cavity or pelvis. The external parts of the male reproductive system include the penis, the scrotum and the testicles. The opening of the urethra — the tube that transports both semen and urine out of the body — is located at the tip of the glans penis.

These parts are internal; the vagina meets the external organs at the vulva, which includes the labia, clitoris, and urethra. The vagina is attached to the uterus through the cervix, while the uterus is attached to the ovaries via the fallopian tubes. At certain intervals, the ovaries release an ovum, which passes through the fallopian tube into the uterus. If, in this transit, it meets with sperm, the sperm penetrates and merges with the egg, fertilizing it. The fertilization usually occurs in the oviducts, but can happen in the uterus itself.

The male reproductive system consists of a number of sex organs that play a role in the process of human reproduction. These organs are located on the outside of the body and within the pelvis. The main male sex organs are the penis and the testicles which produce semen and sperm , which, as part of sexual intercourse , fertilize an ovum in the female's body; the fertilized ovum zygote develops into a fetus , which is later born as an infant. The corresponding system in females is the female reproductive system. The penis is the male intromittent organ.

Human Reproductive System is an internal organ system via which humans reproduce and bear offspring. The reproductive system is a collection of organs both internal and external that works together to serve the purpose of procreation. Due to the vital role of procreating, scientists have considered this system as the most important one in the human body. The male and female sex has their own unique reproductive system. The function of the male reproductive system is to produce and deposit sperm and the female produces egg cells and nourishes the fetus until its birth.

Reproductive system

The human reproductive system functions to produce human offspring, with the male providing sperm and the female providing the ovum.

The human reproductive system functions to produce human offspring, with the male providing sperm and the female providing the ovum. While the ultimate purpose of the human reproductive system is to produce offspring, the proximate purpose is to produce pleasure and induce bonding. This can be seen in our closest relatives, the bonobo chimpanzees, who have sex for a wide variety of reasons including pleasure, bonding, and alleviating tension in addition to producing offspring. The reproductive system or genital system is a set of organs within an organism that work together to produce offspring.

Сьюзан ответила ему теплой улыбкой. Ее всегда поражало, что даже в преддверии катастрофы Стратмор умел сохранять выдержку и спокойствие. Она была убеждена, что именно это качество определило всю его карьеру и вознесло на высшие этажи власти. Уже направляясь к двери, Сьюзан внимательно посмотрела на ТРАНСТЕКСТ.

ГЛАВА 96 Промокшая и дрожащая от холода, Сьюзан пристроилась на диванчике в Третьем узле. Стратмор прикрыл ее своим пиджаком. В нескольких метрах от них лежало тело Хейла. Выли сирены. Как весенний лед на реке, потрескивал корпус ТРАНСТЕКСТА. - Я спущусь вниз и отключу электропитание, - сказал Стратмор, положив руку на плечо Сьюзан и стараясь ее успокоить.  - И сразу же вернусь.

Слышались и другие голоса - незнакомые, ненужные. Он хотел их отключить. Для него важен был только один голос, который то возникал, то замолкал. - Дэвид, прости. Он увидел пятна света. Сначала слабые, еле видимые на сплошном сером фоне, они становились все ярче.
