Reproductive System Of the Human Male 2Reproductive system of human male and female -
See Article History Human reproductive system, organ system by which humans reproduce and bear live offspring. Provided all organs are present, normally constructed, and functioning properly, the essential features of human reproduction are 1 liberation of an ovum , or egg , at a specific time in the reproductive cycle, 2 internal fertilization of the ovum by spermatozoa, or sperm cells, 3 transport of the fertilized ovum to the uterus , or womb, 4 implantation of the blastocyst, the early embryo developed from the fertilized ovum, in the wall of the uterus, 5 formation of a placenta and maintenance of the unborn child during the entire period of gestation , 6 birth of the child and expulsion of the placenta, and 7 suckling and care of the child, with an eventual return of the maternal organs to virtually their original state. Organs and structures of the male and female reproductive systems. For this biological process to be carried out, certain organs and structures are required in both the male and the female. The source of the ova the female germ cells is the female ovary ; that of spermatozoa the male germ cells is the testis. In females, the two ovaries are situated in the pelvic cavity; in males, the two testes are enveloped in a sac of skin, the scrotum , lying below and outside the abdomen. reproductive system of human male and femaleSistema reproductor femenino What Is Reproduction? Reproduction is 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 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 ZYE-goat. The zygote goes through a process of becoming an embryo and developing hu,an a fetus. The male reproductive system and the female reproductive system both are needed for reproduction.
Development of the reproductive organs
Humans, like other organisms, pass some characteristics of themselves to the next generation. We do this through our genesthe special carriers of human traits. The genes that parents pass along are what make their children similar to others in their family, but reproductiive what make each child unique. These genes come from the male's sperm and the female's egg. What Is the Female Reproductive System?
Respiratory System
The external part of the female reproductive organs is called the vulva, which means covering. Located between the legs, the vulva covers the opening to the vagina and other reproductive organs inside the body. The fleshy area located just above the top of the vaginal opening is called the mons pubis.
Two pairs of skin flaps called the labia which means lips surround the vaginal opening.]
Just that is necessary.
I think, that you are not right. I can defend the position. Write to me in PM, we will discuss.
Bravo, brilliant phrase and is duly
