Human Reproductive System
Reproductions in humans
The functions of the male reproductive system
To develop and reproduce sperms
To transfer sperms to the female reproductive system
Organ of male
Testis
To develop and produce the male reproductive cells called sperms
Penis
To transfer the sperms to the female reproductive system
When the tubes connecting the testis and the penis are cut and tied up, the sperms cannot travel from the testes to the penis
The female reproductive system
The functions of the female reproductive systems
To develop and produce eggs or ova
To allow the development of a fertilised egg into a baby
Organs
Womb
To allow the development of a fertilised egg into a baby
Vagina
A muscular tube where sperms are deposited
Ovary
to develop and reproduce the female reproductive cell called eggs or ova
When the tubes near the ovaries are blocked or tied up, the sperms will be blocked from coming into contact with the eggs released from the ovaries.As a result, the eggs will not be fertilised and the woman will not be able to have children
Fertilisation
Fertilisation is the fusion of the nuclei of a sperm and an egg to form a fertilised egg
A mature egg is released from one of the ovaries every month generally
During mating, the male releases a large amount of sperm through the penis into the female vagina.
The large number of sperms increases the chance for one sperm to fertilise the egg successfully
The sperms use their tails to swim towards the egg and surround the egg
Only one sperm can enter the egg successfully and the rest of the sperms will die.
While moving down the womb, the fertilised egg starts to divide to form many cells which looks like a ball of cells
In the womb, the ball of cells will form the developing baby called foetus. The umbilical cord connects the foetus to the mother
there are blood vessels in the umbilical cord. The functions of blood vessels in the umbilical cord are:
To obtain nutrients and oxygen from the mother to the baby
To remove waste substance and carbon dioxide from the baby to the mother

After the sperm fuses with the egg, the egg is said to be fertilised
