This video explains female reproductive system in Humans from the lesson "How do organisms reproduce" a CBSE class X lesson from NCERT Science Text Book. In this video we will see the different parts of human female reproductive system and their specific jobs
Female Reproductive System
In this video we will see the structure and functions of human female reproductive system
Let us see the different parts of the female reproductive system. They are Ovaries, fallopian tubules, uterus, cervix and vagina.
Ovaries : There are pair of ovaries that contain the pre matured egg cells.
Oviducts: The two oviducts unite into an elastic bag-like structure known as the uterus.
Uterus: It is called the womb where the implantation and development of baby takes place
Cervix. The uterus opens into the vagina through the cervix.
Vagina: It is the passage where sperms are deposited by the penis of male reproductive system during sexual intercourse.
Now let's see the production of female gametes:
When do girls start producing egg cells?
When a girl is born, the ovaries already contain thousands of immature eggs.
By reaching puberty, the eggs start maturing.
One egg is produced every month by one of the ovaries.
The egg released by the ovary is collected in the fallopian tubule.
It is the place where the fertilization takes place by the fusion of sperm and egg cells.
Then how do the sperms reach fallopian tubule?
The sperms get deposited in the vagina of the female reproductive system by the penis of the male reproductive system during sexual intercourse.
The sperms travel towards fallopian tubule and finally reaches the egg cell and fertilizes it.
The fertilized egg, the zygote, gets implanted in the lining of the uterus, and starts dividing.
The hormones secreted by the ovaries prepares the uterus to receive and nurture the growing embryo
The walls of the uterus becomes thick and richly supplied with blood to nourish the growing embryo.
Placenta is a special tissue that helps the embryo to get nutrition from the mother's blood.
It is embedded in the uterine wall and contains and provides glucose and oxygen to the embryo.
Placenta also transfers the waste generated by the embryo into the mothers blood.
The development of the child inside the mother’s body takes approximately nine months.
The child is born as a result of rhythmic contractions of the muscles in the uterus.
