Genitals are ... The human reproductive system

As is known, the human reproductive system is intended for the reproduction of offspring. Female and male genitalia differ significantly from each other. Next, all the sexual organs of man, their destination, will be examined.

Female genital organs

The reproductive system of a woman performs several important functions. This is the formation of female eggs, which are necessary for reproduction. They are also called mature ovules. After the formation, they are transported to the place where fertilization will take place. Usually it is the fallopian tubes. The next step in the fertilization of the egg is to implant it in the uterine wall. This is the beginning of a woman's pregnancy. If this does not happen, then menstruation begins. Another function of the female reproductive system is the production of sex hormones that support the cycle of reproduction.

The structure of the female reproductive system

The system consists of both internal parts and external ones. Genitals are external organs, whose function is to ensure the penetration of sperm into the body, as well as to protect the internal organs from infections.

External organs of a woman

To the external genitals of a woman are:

• Large labia. They embrace and protect themselves small labia. The structure of the genitals is comparable to the male scrotum, since the large lips are relatively large and fleshy. They contain sweat glands and glands secreting grease. During the transitional age, they are covered with hair follicles.
• Small labia can be really small - a width of only 5 centimeters. They surround the entrance to the vagina and are located inside the large labia.
• Clitoris is a small sensitive organ formed at the point of convergence of the labia minora. The genital organ of a man is often compared to him. The clitoris is covered with a skin fold, like a penis. Also, it is sensitive to touch and erect.

Internal organs of a woman

If the genitals are external organs, what are the internal ones?

• The vagina is the channel connecting the cervix and the outer part of the body. It is also called generic pathways.
• The uterus is an empty organ in which the fetus develops. It is divided into two parts: the neck and the main body. It is easily stretched and adjusted to the size of the developing fetus. The canal that passes through the neck allows the seed to get inside, and the blood during menstruation - go outside.
• Ovaries are small oval glands located on both sides of the uterus. They produce eggs and hormones.
• Fallopian tubes are called narrow tubes attached to the top of the uterus. They go through mature ovules in the uterus. Fertilization occurs in these tubes. The fertilized egg then moves to the uterus, where it develops and develops.

Male reproductive system

Unlike the female, most of the male system is outside the body. This is due to the fact that a man participates only in conception, and not in the formation of the fetus and his bearing.

Male external organs

The scrotum, penis and testicles belong to the external genitalia.

• The penis is the male organ used in sexual intercourse. It consists of a root attached to the stomach, a stem, and also a head, which is a cone-shaped part at the end. The head is covered with the foreskin, which some are removed for various reasons. The urethra and the tube transporting the seed and urine are at the end of the organ. The genital organ contains a very large number of nerve endings, which are extremely sensitive. The penis consists of three chambers, which, in turn, consist of a spongy tissue. The cavities of this tissue are filled with blood at the moment of excitement. This allows you to conduct intercourse.

• Male genitalia is not only a penis, but also a scrotum. It is a bag containing testicles and many blood vessels and nerves. It regulates the temperature of the testicles, since for the production of the seed it should be slightly lower than the total body temperature.
• Testicles - oval organs of small size, located in the scrotum and attached to the cord. These organs are responsible for the production of male hormone and sperm. Inside them there is a large number of tubules - tubules. They produce sperm.

Internal organs of a man

The internal organs of the male system, also called subordinate, are:

• The appendage is a long and curved tube on the back side of the testicle. She carries sperm and stores spermatozoa. They are also responsible for the maturation of sperm.
• The vas deferens are a tube that goes from the epididymis to the pelvic cavity. When preparing for ejaculation, the ducts transfer the mature semen into the urethra.
• The urethra is a tube that carries urine from the body to the outside. In the male body, it also emits seminal fluid. At this time, the flow of urine is completely blocked.
• Seminal vesicles are sacs attached to the ducts that lead to the seed, near the base of the bladder. They produce fructose. It is a liquid that is saturated with sugar. It serves as a source of energy for the sex cells, which enables them to move. It is the liquid of these vesicles that predominates in the total volume of the seminal fluid of the male, which is also called the ejaculate.
• The prostate, or prostate gland, is an organ that is comparable in size to a walnut. It is lower than the bladder. Prostate adds to the seminal fluid additional elements that feed semen. The urethra, ejecting ejaculate at orgasm, passes just through the middle of the prostate gland.
• Bulbourethral glands, also called Cooper, are a bean-sized structure. They are located below the prostate on the sides of the urethra. These glands form a transparent fluid that enters directly into the urethra. It is necessary for lubrication and elimination of any acidity after urination.

Conclusion

So, now it became clear why the human reproductive system is needed, what is different for a woman and a man, what is genitalia. This is all an integral part of the human body, without which life on the planet would be impossible. It is very important to leave this system healthy, to produce a full-fledged offspring and thereby maintain life in the world.
